Former star Liberal recruit Steven Guilbeault confirmed Wednesday his exit from politics, saying he’s decided he needs to pursue his fight against climate change in a different way.

Prime Minister Mark Carney told reporters he’s known for some time that his former cabinet minister could leave and said he understands the decision.

Mr. Guilbeault, who represents a Montreal riding, said he will remain in the governing caucus until he resigns his seat later this summer.

“After almost seven years as a Member of Parliament and Minister, I have come to the conclusion that it is time for me to pursue my fight for environmental protection and the fight against climate change in a different way,” Mr. Guilbeault said in a statement posted to social media.
