A joke about the new pound coin has been named the funniest of the Edinburgh Festival Fringe.

Ken Cheng won the tenth annual award for Dave's Funniest Joke Of The Fringe.

The joke, from his show Ken Cheng: Chinese Comedian, won 33% of a public vote on a shortlist of gags picked by comedy critics.

He was rewarded for the line: "I'm not a fan of the new pound coin but then again I hate all change."

Previous winners of the award include Tim Vine, Stewart Francis and Zoe Lyons. Cheng studied maths at Cambridge for a year before dropping out to play online poker professionally.

His big break in showbiz came when he reached the final of the 2015 BBC Radio New Comedy Award. On winning the Dave prize, Cheng said: "I am very proud to have won. As a tribute, I will name my firstborn son after this award and call him 'Joke of the Fringe'."

Frankie Boyle came second in the poll for his line: "Trump's nothing like Hitler. There's no way he could write a book."

The award, which was voted on by 2000 people, lists jokes anonymously to avoid any bias towards well-known comedians.
