After months of speculation about his future, British Columbia Premier Glen Clark resigned this weekend. He gave notice on his way into a meeting of the NDP caucus Saturday afternoon.

The new premier designate is Dan Miller.

The caucus meeting was called Friday, after confirmation that Clark was the subject of a criminal investigation into the granting of a conditional casino licence to Dimitrios Pilarinos, a friend of Clark.

Clark says he made the decision after realising it would be wrong for him to continue as premier.

"No premier should be driven from office by the existence of an investigation that remains incomplete and much of which has already been disproven," he said, adding "I've concluded it would be wrong of me to continue."

Despite his resignation, Clark continues to insist he has done nothing wrong, that the accusations against him are "scurrilous" and the investigation will prove it.

"I'm completely confident I will be exonerated and cleared," Clark said in a relaxed tone.

But the premier also says he knew in March, when his house was raided, that he would eventually have to resign.

This is the third resignation by a B.C. premier over allegations of misconduct in 10 years.

Deputy Premier Dan Miller was appointed interim premier by unanimous decision from the NDP caucus Saturday afternoon. He will be sworn in early next week. Miller says he will remain premier only until a leadership convention is held. Miller will not be a candidate.

Clark was formally informed of the criminal investigation on Tuesday by his attorney general. Dosanjh learned of it himself March 3 -- the day after RCMP conducted a search of the premier's home -- but was not able to inform the premier.

The announcement of the criminal investigation Friday came just hours after a B.C. judge agreed to release some of the information that helped RCMP get their search warrant to raid 14 locations around Vancouver, including Clark's home.

About half of the information was released, including surveillance reports and allegations from an unnamed source. The information did not include details from wiretaps.

The unnamed source alleges Clark received renovations to his home in exchange for political influence.

Dosanjh says no charges have been laid. That decision will be left to the police, he says.
