May confirms ex-New Democrat Pierre Nantel is running as a Green candidate

It's official: former NDP MP PierreNantel is switching teams and running for the Greens in the federal election.

The New Democrats announced Friday that they had removed Nantel as their candidate for LongueuilSaint-Hubert, following what the party called "confirmed reports" that he was "is in discussions with another party to run under their banner."

On Monday, Green Party Leader Elizabeth May confirmed Nantel will be running as a Green candidate.

"PierreNantelis a climate leader, and he is one of the most passionate MPs I have encountered in the House of Commons," said May in a statement.

His switch seems to have come as a shock to his former party.

NDPdeputy leader Alexandre Boulerice said he had a short conversation with Nantel last week, during which he talked about the issueof climatechange, which is a key part of the NDP's platform.

"It's not a good day for the NDP," Boulerice said Friday. "I don't understand the reasons or the motivations of Pierre."

Nantelwas first elected in2011 as part of the NDP's 'orange wave' in Quebec. He was narrowly re-elected in 2015, beating the Liberal candidate by less than 700 votes.

The NDPsaid it will now look to nominate a new candidate in the riding.

The Liberals already have recruited a star candidate to run in the riding. Rjean Hbert, a former provincial health minister,announced in Julythat he would be running for the Liberals.
