Pat O'BrienPat O’Brien (left), the Liberal Member of Parliament for  the southern Ontario riding of London-Fanshawe, has called a press conference for 11 am this morning to discuss his future. O’Brien, earlier this week, called a Liberal MP Sarmite Bulte a “blonde bimbo” after she referred to him as a rat for considering leaving the Liberal caucus over the sponsorship scandal.

O’Brien conceded that he was thinking about it and that senior Conservative officials were talking to him. He did say though that he wanted to wait until a major report from a Commons committee he chairs was out next week. Apparently, he doesn’t want to wait anymore.

O’Brien is among the most vocal  opponents within his caucus of the Liberal plans for legalize same-sex marriage.

He was first elected — as a Liberal — in 1993 and has won four elections as a Liberal.
