Fawlty Towers has been named as the greatest, with credit going to a ‘six-foot-five comic genius’.

The list of the 20 best British sitcoms has been compiled by a panel of television experts for Radio Times magazine.

John Cleese has been credited with channelling his rage as the highly-strung Basil Fawlty, proprietor of a sub-par Torquay hotel, which made the series a hit.

Fawlty Towers came top of the list ahead of other series including Father Ted, Blackadder, I'm Alan Partridge and Only Fools And Horses.

The BBC series ran for just two series of six episodes each in the 1970s.

Speaking to the Radio Times, co-writer and co-star of Connie Booth said: ‘Fawlty Towers succeeds, I think, because it allows infantile rage and aggression a field day in a buttoned down, well-mannered English society.

‘It's unique in being a farce, with all the plot surprises and precision that the style requires. And it doesn't hurt that the star of the show is a six-foot-five comic genius. If he was shorter I can't imagine how it would have worked.’

Cleese added: ‘I was very lucky to be working at the BBC when decisions were taken by people who had actually made programmes. What a cast.’

Channel 4 sitcom Father Ted, penned by Arthur Mathews and Graham Linehan, came second in the list. I'm Alan Partridge came third, and Blackadder came fourth.

The list was voted for by 42 comedy expert including lauded writers Mathews, Linehan and Richard Curtis, as well Barry Cryer and Alison Graham.

Graham said: ‘When we find a comedy that does make us laugh, that brings a quick hit of joy into our lives, and we treasure it for ever.

‘In our memories, great comedies are pearls that become more burnished and beautiful through the years. Absence really does make the heart grow fonder.’
