Comedian Robert Webb has said he does not yet know whether he will be asked to be best man at David Mitchell’s forthcoming wedding to Victoria Coren.

While his comedy partner was best man at his own wedding to comedian Abigail Burdess in 2007, the 39-year-old has admitted that he is still waiting to hear whether Mitchell will return the favour, after he recently announced his engagement.

David hasn’t asked me yet,” Webb revealed. “We’ll see. I don’t know whether to say I’m on tenterhooks. I’ll find out sooner or later, but there are plenty of other good candidates so if it’s not me it’ll be someone terrific.

“He’s got plenty of friends and a brother, so I won’t be too heartbroken if it’s not me. But if it is I’d better start working on that speech.”

The pair first found fame as dysfunctional housemates in the Channel 4 sitcom Peep Show, and are due to begin filming the eighth series of the show this summer.

And despite having played the role of Jez for almost a decade, Webb admitted he still enjoys slipping into character.

“I guess I know what I’m doing now,” he said. I’ve been playing him for getting on for 10 years.

“He’s totally immoral and he’s a bad guy in many ways, but he’s very lovable. He never really learns, but playing Jez is fun because he does and says things the rest of us would never dream of.”
