Amazon.co.uk say the £4.86 'Borat Mankini Thong' has become a surprise summer bestseller for them after featuring in a spoof video by members of the Great Britain Olympic rowing team.

In the clip called 'Rowing, My Way', members of the team singing Frank Sinatra's My Way, with one member sporting the Borat-like swim suit on top of a mountain.

A spokesperson for Amazon.co.uk said: "With the success of Britain's Olympians in the pool, we'd expected to see a rise in swimwear sales, but the Mankini's success has taken us by surprise.

"Maybe the rowers have started an unlikely fashion trend - look out for a Mankini on a beach near you this summer!"
