Under-seige Toronto mayor Rob Ford has denied snorting cocaine with prostitutes at a booze and drug-fuelled party on St Patrick's Day.
At a chaotic press conference, an angry Ford said that the latest in a string of lurid allegations had sent him "over the line" and were "100% lies".
According to reports in the Telegraph, married father-of-two Ford was caught "extremely drunk" in the mayoral office with a woman "who may have been an escort or prostitute" by staff.
It was also alleged that he verbally abused a taxi driver by calling him a "Paki" and later danced in a nightclub like "someone would act while on cocaine".
Citing the death of his father, independent Conservative mayor Ford claimed that he had been under "tremendous stress" for months and had sought help from healthcare professionals.
He insisted that the latest allegations were lies. He also said sorry for comments relating to claims that he had engaged in oral sex with a staffer.
Ford said: "I want to apologise for my graphic remarks. Yesterday I mentioned it was the second worst day of my life, except for the death of my father. For the past six months I have been under tremendous, tremendous stress.
"I have apologised and have tried to move forward. This has proven to be almost impossible. The revelations yesterday about me and cocaine and prostitutes have sent me over the line. These allegations are 100% lies.
"When you attack my integrity as a father and a husband, I see red."
After finishing his statement, Ford refused to take questions from journalists and caused more chaos by barging them to get out of the room.
Ford was caught on camera taking crack cocaine in a scandal which saw his popularity rate go up after the video was published.
