The B.C. Conservative Party has fired another candidate prior to next month's provincial election, the fourth such firing since last week.

Ron Herbert, the Conservative candidate in the riding of Vancouver–West End, was let go this morning.

Conservative Leader John Cummins gave no reason for the move, which comes after a full re-vetting of all B.C. Conservative candidates.

Cummins has also announced that a senior volunteer responsible for vetting candidates has been let go, after a series of embarrassing revelations about candidates.

On Thursday, the B.C. Conservatives fired their Boundary–Similkameen candidate Mischa Popoff for his remarks about women and single mothers in a local newspaper.

Earlier in the week, the party fired Vancouver–False Creek candidate Ian Tootlill over comments he made on Twitter, and North Vancouver–Lonsdale candidate Jeff Sprague was dropped after allegedly driving while impaired.

Prior to the Conservative firings, the B.C. NDP dropped Kelowna–Mission candidate Dayleen Van Ryswyk on the first day of the provincial election campaign over controversial comments made on a local media website.
