OTTAWA -- A NDP MP with a history of Twitter outrage and shooting from the lip is leaving the Twitterverse after another profanity-laced thumb tirade, but won't be disciplined for his latest meltdown.

Pat Martin -- who is also the subject of a $5 million lawsuit for comments he made about a robo-calling firm -- blew a gasket Wednesday night because he wasn't invited to a funding announcement in his Winnipeg riding.

In a series of Tweets, he told one participant to "F--- off," said he was "fed up" with the "rat-faced whores" at the Conservative party, and regurgitated the sex life of political foe Public Safety Minister Vic Toews, the senior minister for Manitoba.
