Welsh people are top of the trumps in Britain

A poll has found 30 per cent of those from the Valleys let one go at least 20 times a day - which is three times more than the UK average.

The research, carried out by Branston Beans, also revealed 11 per cent of men in Britain trump loudly 20 times or more per day compared to just nine per cent of women.

The NHS says it is normal to pass gas between five and 15 times a day.

David Williams, from Tenby in south west Wales, claims he doesn't "have a clue" how many times he cuts the cheese every day.

He said: "I really wouldn’t have a clue, but I’m guessing 50 plus. You’d really have to ask my wife, who has to put up with it. But she is so used to it she probably barely notices anymore, unless it’s a really bad one."

A Branston spokesperson added: "These findings remind us that farting is universal."
