BC Liberal Leader Andrew Wilkinson is challenging premier John Horgan to a public debate on proportional representation.

"This fall, British Columbians will vote on whether to drastically change our democratic system with proportional representation," Wilkinson said in a video posted to Facebook on Monday.

"John Horgan and the NDP have broken their promise to give British Columbians a simple yes or no choice. They've stacked the deck with a complicated, confusing referendum that could throw our province into chaos, and strictly limited how much information can be shared with voters," he said.

The Liberals are on record as opposing the change, as presented in a mail-in referendum that will be held Oct. 30-Nov. 30.

Voters are being asked to consider three options for proportional representation, which the NDP supports.

Horgan previously has said a party that wins 40 per cent of the vote shouldn't receive 100 per cent of the power.

B.C. currently uses a first-past-the-post method of voting, in which the party with the most elected MLAs gets to govern, whether or not it wins a majority of the popular vote.

This will be B.C.'s third referendum on electoral reform in 15 years – the first two soundly rejected proportional representation.

Wilkinson said he's challenging Horgan to the debate "because the people of B.C. deserve every opportunity to hear both sides of the argument, get the facts, and be informed."

There is no word yet on whether Horgan will accept the challenge.
