North Korean Leader Kim Jong-Un's Mystery Rollercoaster Companion Revealed As British Diplomat Barnaby Jones (PICTURES)

A mystery Westerner spotted riding a fairground rollercoaster with Kim Jong-Un and his entourage has been identified as British diplomat Barnaby Jones.

The snap caused a flurry of speculation as to the identity of the man, who accompanied the North Korean leader on a trip to the Rungna People's Pleasure Ground in Pyongyang last month.

Jong-Un brought along his wife Ri Sol-Ju for the fun-filled jaunt, which saw them fondling octopus tentacles and generally having a laugh.

Dressed in rolled-up shirtsleeves, the mystery guest stuck out in contrast to Jong-Un's smartly suited companions. Mother Jones has since confirmed he is Mr Jones, a junior diplomat with the British Embassy in Pyongyang.

The British Foreign and Commonwealth Office in London has also verified his identity, with a spokesman describing the amusement park visit as "unusual".

Charles K Armstrong, director of the Centre for Korean Research at Colombia University, said: "That is quite surprising to show a foreigner in such proximity to Kim Jong-Un. Normally pictures of the leader with a foreigner would be carefully staged."

There has been speculation Jong-Un and his bride may have been married for as long as three years and have a son.

Late leader Kim Jon-Il chose Ri Sol-Ju to be his son's wife as early as 2008, one analyst told the South Korean Korea Times newspaper, quoted by news agency AFP.

Jong-Un's new wife studied music, and was born in 1989, according to Yonhap news agency, making her younger that her husband who is believed to be in his late 20s.

In recent months, speculation had mounted over the identity of the mystery young woman frequently pictured with the leader, with reports suggesting she could be the leader's girlfriend or his sister.

However last month's shock announcement of the nuptials took the world by surprise.

The most recent pictures of the Supreme couple relaxing at the theme park further fuel speculation that the new leader may be relaxing his approach to international relations.

Ri Sol-Ju's Western hairstyle and dress were first noticed when she was seen pictured next to Jong-Un at the 18th anniversary of the death of North Korea founder Kim Il Sung, the new leader's grandfather.

She was also by Jong-Un's side at a concert where costumed Disney characters performed for the couple and a host of generals.

North Korea's aggressive nuclear arms programme and long-running animosity with the West means American characters such as Minnie mouse, Tigger and Dumbo are hugely unlikely presences in the communist nation.
