British athletes competing at the Winter Olympics have been advised not to wear their official team kit in Sochi.
The British Olympic Association (BOA) have warned members of Team GB to "keep a low profile" while in Russia, particularly when travelling through Moscow.
Officials say it is part of a "common sense approach", rather than a response to a specific threat.
Members of Team GB for the Sochi 2014 Winter Olympics line up
"The safety and wellbeing of the Team GB delegation competing in Sochi remains our number one priority," Sky News reported the statement as saying.
"We are in daily contact with the relevant authorities in the UK including the Foreign and Commonwealth Office.
"While we have not received any information or advice suggesting an increase in the threat level, we are taking a common sense approach in recommending that team members wear less overtly branded Team GB kit during their journey to Sochi.
"This advice is similar to guidance being offered to other delegations by their respective National Olympic Committees."
Athletes are due to arrive in the Olympic village, which opens today, over the next 48 hours.
Gay Athletes At The 2014 Sochi Olympics
Anastasia Bucsis(01 of38)
The Canadian long-track speedskater took a brave step in September when she publicly came out as a lesbian at Calgary's Pride Parade. Bucsis told the Globe and Mail that her announcement was important. “I could never promote that message of concealing who you are with all of this going on in Russia," she said. CORRECTION: An earlier version of this slideshow stated that Sochi will be Bucsis' first Olympics. She competed in Vancouver and Sochi will be her second Olympics.

Belle Brockhoff(02 of38)
The 20-year-old gay Australian snowboarder is also headed to her first Games. While she said she wants to focus on her performance instead of politics, she plans to don merchandise from Principle Six, a clothing company inspired by the Olympic Committee Charter's sixth principle, which states that “any form of discrimination with regard to a country or a person on grounds of race, religion, politics, gender or otherwise is incompatible with belonging to the Olympic Movement." The Committee confirmed this also includes sexual orientation. (credit:(Photo by Ryan Pierse/Getty Images))
Ireen Wüst(03 of38)
The Dutch champion speedskater isn't as open about her sexuality as the other two Olympians. While she came out in 2009 by casually mentioning she was dating fellow speedskater Sanne Van Kerkhof, she'd prefer the media focus on her talents. 'I want to talk about ice skating', she reportedly said in a 2010 interview. These are not Wust's first Games. She's nabbed gold twice before - in the 2006 and 2010 Winter Olympics.

Brian Boitano(07 of38)
The retired Olympic figure skater, who won a gold medal at the 1988 Games, will also be part of the symbolic U.S. delegation to Sochi.

(credit:Associated Press)
Billie Jean King(08 of38)
The retired tennis great and two-time Olympian will also be part of the U.S. delegation of LGBT athletes. King, who is a 39-time Grand Slam champion, was outed in 1981 and told HuffPost "it's very difficult" to be a gay woman in sport. (credit:HuffPost Live)

Orlando Cruz(11 of38)
History was made in October 2012 when active professional featherweight boxer Orlando Cruz of Puerto Rico came out. He said in a USA Today article, "I've been fighting for more than 24 years and as I continue my ascendant career, I want to be true to myself. I want to try to be the best role model I can be for kids who might look into boxing as a sport and a professional career."He continued, "I have and will always be a proud Puerto Rican. I have always been and always will be a proud gay man." (credit:AP)
Jason Collins(12 of38)
Jason Collins made history in April of 2013 by coming out, making him the first openly-gay professional male athlete in a major sport. Collins is a free agent who has played for the Washington Wizards and the Boston Celtics. "I never set out to be the first," Collins told ABC's George Stephanopoulos during an interview that first aired during "Good Morning America".

Brittney Griner(13 of38)
Brittney Griner is the 2013 number one Women's National Basketball Association (WNBA) draft pick and newly Phoenix Mercury player.

Megan Rapinoe(14 of38)
The 27-year-old U.S. Olympic soccer player spoke frankly about her sexuality in an interview with Out magazine, saying she is a lesbian and in a committed relationship with a woman.While her statement may seem bold, the 27-year-old Rapinoe told Out's Jerry Portwood that she'd just never been asked directly. "I think they were trying to be respectful and that it's my job to say, 'I'm gay,' she said. "Which I am. For the record: I am gay."Rapinoe, who's been dating her girlfriend -- identified in the magazine only as an Australian soccer player -- for three years, also took time to chat about homophobia in sports and, more specifically, female athletes' perspective on the subject."I feel like sports in general are still homophobic, in the sense that not a lot of people are out," she said. Still, she added, "In female sports, if you're gay, most likely your team knows it pretty quickly. It's very open and widely supported. For males, it's not that way at all. It's sad."

Kwame Harris (15 of38)
Although his coming out wasn't ideal when news broke that he was facing charges for assaulting a former boyfriend, former San Francisco 49er Kwame Harris spoke out against fellow 49er, Chris Culliver, who said he didn't believe gays had a place in the locker room, saying: "It’s surprising that in 2013 Chris Culliver would use his 15 minutes to spread vitriol and hate. I recognize that these are comments that he may come to regret and that he may come to see that gay people are not so different than straight people.” (credit:Getty Images)
John Amaechi (16 of38)
In 2007, Amaechi -- who played at Penn State and spent five seasons in the NBA with Orlando -- identified himself as a gay man in his book "Man in the Middle." Four years later, Amaechi criticized Kobe Bryant after the five-time NBA champion used a gay slur during a game. "There's only one contemporary meaning for that," he said. "We have to take it as unacceptable as a white person screaming the N-word at a black person. I can tell you that I've been called a f--got fairly routinely, and yet people seem to hold off on calling me the N-word. We've got to mirror that progress." (credit:AP)
Gareth Thomas (17 of38)
Thomas's decision to confirm his sexuality while still an active rugby player was praised by LGBT rights advocates as a brave move. Though others have since followed suit, Thomas hoped people who eventually consider his sexuality as irrelevant. "What I choose to do when I close the door at home has nothing to do with what I have achieved in rugby," he told The Guardian. "I'd love for it, in 10 years' time, not to even be an issue in sport, and for people to say: 'So what?'" (credit:Getty )
Martina Navratilova(18 of38)
The Prague-born tennis pro, who came out as bisexual in 1981, is credited with having "expanded the dialogue on issues of gender and sexuality in sports," according to ESPN. "Martina was the first legitimate superstar who literally came out while she was a superstar," Donna Lopiano, executive director of the Women's Sports Foundation, said. "She exploded the barrier by putting it on the table. She basically said this part of my life doesn't have anything to do with me as a tennis player. Judge me for who I am." (credit:Getty )
Matthew Mitcham (19 of38)
The Olympic diver, who took home the gold medal in 2008 in the ten meter platform, revealed his sexuality in an exclusive interview with The Sydney Morning Herald. Mitcham, then 20 years old, credited partner Lachlan with helping him battle depression and emotional burnout in the years before his Olympic triumph. (credit:Getty )
Glenn Burke(20 of38)
Glenn Burke became the first former professional baseball player to come out of the closet when he discussed his sexuality in 1982 in an Inside Sports magazine article and on "The Today Show" with Bryant Gumbel.The athlete was drafted by the Los Angeles Dodgers in 1976 to play in the outfield. Out to his family and friends, Burke was soon traded to the Oakland A's and rumors about his sexuality began to swirl. His glass closet case wasn't entirely welcomed in the locker room, and he left the A's shortly after his arrival in Oakland. Burke retired from baseball at the age of 27."Prejudice drove me out of baseball sooner than I should have," Burke said in an interview with the New York Times in 1994. After that, Burke, who became revered in the Castro, played in Gay Softball World Series and may have even invented the high five, passed away from AIDS in May 1995 at the age of 42.See the full story here.

I woke up in complete freedom today. The sky is wide open." (credit:Getty Images)
Johnny Weir (22 of38)
Known as much for his colorful fashion sense as his slick moves on the ice, Weir faced intense media scrutiny over his sexual orientation before finally coming out in his recently published memoirs. "With people killing themselves and being scared into the closet, I hope that even just one person can gain strength from my story," Weir said at the time. "A lot of the gays got downright angry about my silence. But pressure is the last thing that would make me want to 'join' a community." (credit:Getty )
Billie Jean King (23 of38)
Unfortunately, the tennis pro's 1981 outing was not her choice; she was forced out when her former female lover sued her for palimony and nearly lost all of her commercial endorsements as a result. But her career was far from over, and in 2000, she became the first open lesbian ever to coach an Olympic team. (credit:AP)
Heather Cassils(24 of38)
Heather Cassils is a Canadian performance artist, body builder and personal trainer now living in Los Angeles. Unlike other artists working in more traditional mediums, Cassils uses her body to investigate issues related to gender, mass consumption and the industrial production of images, among others. Her conceptual pieces, which have been performed in museums and galleries around the world, also highlight transgender or "genderqueer" themes, like in "Cuts: A Traditional Sculpture," for which she spent 23 weeks documenting herself building her body to its maximum capacity by following a strict weightlifting regime, consuming the caloric intake of a 190-male athlete, and taking mild steroids. She also starred in Lady Gaga's "Telephone" video.Earlier this year Cassils told The Huffington Post:
"If you're not going to exist as your biologically-assigned gender or you're not operating [as a transgender person] on one end of the gender spectrum, then you end up in that in between space, inviting that scrutiny... I'm trying to push or create a kind of visual language for my subjectivity -- trying to create visual options. You can tap into people's psyches and have them imagine things that they don't yet have words for. I think that's very powerful. I'm trying to create a slippery language, one -- much like my body -- that doesn't fit."(credit:Heather Cassils and Manuel Vason, Collaboration, London 2013)
Greg Louganis (25 of38)
In 1995, the Olympic diving hero (who became the first man in 56 years to win two gold medals in diving when he captured the platform and the springboard events in Los Angeles 11 years earlier) shocked fans when he decided to come out as both gay and HIV-positive on The Oprah Winfrey Show. "People who were close to me -- family and friends -- they knew about my sexuality," he said in 2006. "I just did not discuss my personal life, my sexuality with the media. That was my policy."

Billy Bean (30 of38)
Formerly of the San Diego Padres, baseball player Billy Bean came out in 1999, five years after he retired. Now, however, he says he has regrets about ending his baseball career after just six seasons. "If I had only told my parents, I probably would have played two or three more years and understood that I could come out a step at a time, not have to do it in front of a microphone," he is quoted by Outsports as saying. "And I was completely misguided. I had no mentor. I think that's where the responsibility comes in for people who have lived that experience, and we take for granted that everybody's adjusted and gets it." (credit:Getty )
Wade Davis (31 of38)
Former NFL player Wade Davis came out in 2012 after leaving the sport. When San Francisco 49er Chris Culliver spewed anti-gay remarks about gay players in the NFL just before taking the stage of Super Bowl XLVII, Davis spoke up against Culliver and said: "I thought, ‘Wow, this is going to help us have this conversation during the biggest game of the year,’ but then I also thought, ‘Wow, there’s a lot of players who are closeted in the NFL that are going to go deeper into the closet because of these comments.” (credit:YouTube)
Rosie Jones (32 of38)
The pro-golfer, who won 13 events during her 21 years, came out in a 2004 New York Times editorial. "You see, my sponsor, Olivia, is one of the world's largest and most respected companies catering to lesbian travelers, and this represents the first time a company like this has sponsored a professional athlete -- a gay professional athlete," Jones wrote. "Inherent in this sponsorship is my coming out. It's a bit of a curiosity, because I've never been in the closet. For more than 25 years, I've been very comfortable with the fact that I'm gay...I have never, until now, felt the need to discuss it in the news media." (credit:Getty )
Robert Dover (33 of38)
The champion rider, who competed in six consecutive Olympics, says he's never had much of a problem with being open about his sexual orientation in the equestrian world. Still, as he he told Outsports, "I did not connect my social life to my work life for many years, and while I never ran away from the issue of my homosexuality, I must admit that I had no real interest in bringing attention to it, especially with the press...what changed everything was a combination of meeting my soul-mate Robert Ross, whom I was so proud to be with that I wanted everyone to know, and the AIDS epidemic which affected so many people dear to me."

Ilana Kloss(34 of38)
The South African-born commissioner of World Team Tennis has also been the partner of Billie Jean King for more than 20 years. She also credits King with encouraging her to pursue her career.

Sochi Winter Olympics chief Dmitry Chernyshenko dismissed safety concerns by insisting the city will be the "the most secure venue on the planet" during next month's Games.
Fears of a terrorist attack were heightened last month by a twin bomb attack on the nearby city of Volgograd which killed 34 people.
But Chernyshenko, who is both president and chief executive of the Sochi Games, says an unprecedented security programme will ensure the safety of visitors to the Games without adversely affecting the Olympic atmosphere.
Chernyshenko said: "Sochi is the most secure venue on the planet at the moment and I can assure you from my personal experience of previous Games is will be one of the most security-friendly Games.
"All the procedures will be very gentle and reasonable. It is important to remember the Olympics is a global event and security is also a global multi-national [operation], and we are doing our best to deliver Sochi as the safest Games for everyone."
