Martin Brundle has confirmed that he will leave the BBC to become part of the Sky Sports Formula 1 broadcast line-up from 2012.
The former F1 racer and Le Mans winner made the announcement in his Sunday Times newspaper column, saying that the fact that Sky will carry the whole season live - while the BBC will only show 10 races live and the rest in delayed highlights programmes - was key in his decision.
"In 2012 I will be working with Sky Sports F1 television," Brundle wrote. "The fact that their newly-announced and dedicated F1 channel will have no in-race advertising was a key factor, but most importantly I need to commentate on every race live. Recorded and delayed sports television doesn't give me the adrenalin fix I crave.
"There will also be more airtime for the technical features I so enjoy crafting. It's been a privilege to be part of the BBC team, but now I have a new motivation and challenge."
Brundle moved into television commentary after his F1 career ended in 1997, initially with ITV before switching across to the BBC when it reclaimed the rights from 2009. This season he became lead commentator for the first time.
He also announced earlier this week that he would making a racing return in next year's Le Mans 24 Hours, sharing an LMP2 class Greaves Zytek-Nissan with son Alex.
