London Mayor Sadiq Khan has tasked comedian and broadcaster Amy Lame with championing London's nightlife in the wake of the closure of world famous club Fabric.
The former BBC London radio presenter becomes the capital's first Night Czar and will work with Mr Khan, the Night Time Commission, local authorities, police and Transport for London to help shape the city's future as a 24-hour city and ensure its after-dark economy thrives.
The decision to appoint a Night Czar follows similar appointments in Amsterdam, Berlin and San Francisco.
Mr Khan said: "I'm absolutely delighted to announce the appointment of London's first ever Night Czar.
"The recent closure of the world-famous nightclub Fabric and the threats facing other venues across the capital show why Amy will be a much-needed ambassador for the city after dark."
He added: "Amy is a fantastic hire who will give a big boost to our city's flourishing nightlife, which already attracts millions of visitors each year.
"Her proven track-record of helping save venues, her first-hand experience of the industry over the last two decades as well as her love for London and its nightlife are what make her such a great candidate for the role."
Ms Lame, who was Mayoress of Camden between 2010 and 2011, said: "It's a privilege to be London's very first Night Czar.
"I can't wait to hit the streets and have loads of ideas of what I can do for revellers, night-time workers, businesses and stakeholders.
"For too long, the capital's night-time industry has been under pressure - music venues and nightclubs in particular are closing at an alarming rate."
The closure of Fabric earlier this year was met with fierce criticism by both politicians and figures from the world of music, including Mr Khan and British DJ Goldie.
Islington Council announced its decision to revoke the licence of the Farringdon nightclub on September 7 after finding it had a "culture of drug use" which staff were "incapable of controlling".
The club is expected to appeal the decision at Highbury Magistrates' Court later this month.
