The Londoner, who was banned for two years from 2003 after testing positive for anabolic steroids, blasted to a time of 6.50sec to claim the title for the third year in succession ahead of Harry Aikines-Aryeetey and Craig Pickering at the English Institute of Sport.

Aikines-Aryeetey set a new personal best of 6.55secs in second, with Pickering - who had already said he would not compete in Doha next month even if he won - clocking 6.66.

Mark Lewis-Francis was fourth in 6.67.

Chambers, 31,  won silver at the last World Indoor Championships in Valencia two years ago and is the reigning European champion after victory in Turin last year, where he set a new European record of 6.42 in the semi-finals.

Chambers said: "It's nice but it's still early days, I'm sure the Americans are going to come out and do something crazy.

"It's nice to know I have made the team and can hopefully focus my attention towards Doha now."

Chambers becoming more acceptable to his critics after serving a two year drugs suspension, added: "I've made my fair share of mistakes,

"I just want to put that behind me now and concentrate on what's right for the sport.

"Me running fast is the best thing I can do.

"There's lots of things I wish I'd done correctly but it's done now and I just want to do the best I can while I'm in the sport.

"Running fast is what I enjoy doing and it spurs these guys on as well."
