Doug Ford, the brother of former Toronto Mayor Rob Ford, said he won't run for the leadership of Ontario's Progressive Conservative Party.

Ford made the announcement at a press conference in Toronto on Thursday.

Ford ran for mayor in Toronto's municipal election last month after his brother was diagnosed with cancer. He came in second behind former provincial legislator John Tory.

Ford said he will support Christine Elliott, a provincial legislator and wife of the late federal Finance Minister Jim Flaherty.
