A fourth B.C. New Democrat has announced plans to not run in next year's provincial election.
Coquitlam-Malliardville MLA Diane Thorne was first elected in 2005. NDP leader Adrian Dix thanked the former Coquitlam councillor for her many years of public service, calling her a passionate advocate for social services.
Other New Democrats not seeking re-election next May are MLAs Dawn Black, Michael Sather and Gary Coons.
So far, 14 members of Premier Christy Clark's Liberal caucus have announced they won't be running in 2013.
