As an aside, I just learned that Cliff Richard is the second best selling British male solo artist of all time.
He must be great.
Mike Harding was superb live.

You said 'most successful British comedian of all time', not most successful British stand-up comedian of all time. And you yourself said Gervais has made more money from comedy than Kay.
He's made more money, though not necessarily all from comedy.
I can only think of one straight role he's played off the top of my head.
Rik Mayall (and Ade Edmondson by default)
As GLP said, Hills-Widdicombe-Brooker
Monty Python
Robin Williams, George Carlin, a lot of the early SNL lineup.
Peter Kay
Tim Minchin
Loads of others too. Depends on what in particular you're after, standup or sketch/tv/film? For example, I wouldn't call Simon Pegg a comedian, but he's great when he does comedy.
Can't stand Gervais, but he's obviously appealling to some out there.
I like Peter Kay even more now knowing BCC hates him.

Voice overs for cartons, childrens books and a successful production company.
I love it.
A thread about comedy turns into a row.![]()
Indeed. The children's books were comedy. His production company makes comedy. It's as you said;
'The most successful comedian (in fanancial terms) is Ricky Gervais and he's a right annoying twat.'
