The BC New Democrats' House Leader says the resignation of Premier Christy Clark’s Deputy Chief of Staff brings up lots of questions.

Those questions surround an investigation into a liberal strategy to win ethnic votes using taxpayers' money.

John Horgan says among those questions is whether Kim Haakstad has already been interviewed by the Premier's Deputy Minister, John Dyble, and if she hasn't been, whether that’s possible now she's left the Premier's Office.

Horgan would like an independent investigation to happen.

"But I do know that the deputy to the premier of British Columbia does not have investigatory powers like subpoena powers or ability to search, so much of this work was done on private e-mails, which begs the questions around the Freedom of Information Act."

Haakstad resigned after a memo detailing the strategy was leaked.

Dyble is investigating.
