Paul Merton will host ITV1's British version of Ten Network's Thank God You're Here, it was confirmed today.

The improvised comedy show, which spawned a short-lived American version that aired on NBC in April, features guest stars having to improvise their way through a sketch with only their costume serving as an advance clue as to its subject.

Duncan Gray, ITV's controller of comedy and entertainment, added: "TGYH is a laugh out loud, funny, fresh show, built around Paul Merton’s unrivalled improvisational skill and popularity."

"I'm delighted to be hosting Thank God You're Here," said Merton. "It's a really great
idea: none of the guests have any idea what they're walking into and anything could happen. We've got lots of great scenarios lined up and I can't wait to get started."
