Toronto: Toronto Mayor Rob Ford said on Sunday that a purported video of him smoking crack cocaine does not exist and vowed to seek re-election next year, attacking the media again as a "bunch of maggots."

The mayor of Canada's largest city, speaking on the weekly radio show he hosts with his brother Doug Ford, a city council member, reiterated that the allegations are ridiculous, but he still has not said whether he has ever used crack.

The video has not been released publicly and its authenticity has not been verified. Reports on the gossip website Gawker and in the Toronto Star claimed it was taken by men who said they had sold the drug to Mr Ford. The Associated Press hasn't seen the video.

The Star reported that two journalists had watched a video that appears to show Mr Ford, sitting in a chair, inhaling from what appears to be a glass crack pipe. The Star said it did not obtain the video or pay to watch it. Gawker and the Star said the video was shown to them by a drug dealer who had been trying to sell it for a six-figure sum.
