B.C. Green Leader Andrew Weaver hasn't indicated which party leader he'll back as the next premier of the province.

But a new poll suggests most British Columbians don't want him to keep Christy Clark in power.

An online survey by Insights West indicates that 51 percent of respondents want the B.C. Greens to support the NDP in the legislature in the absence of a majority government.

Only 38 percent want the B.C. Greens to prop up a B.C. Liberal government.

Among B.C. Green voters, 62 percent want Weaver and his caucus to get behind an NDP government. Only 23 percent of B.C. Green voters think the caucus should back a B.C. Liberal government.

Nearly two-thirds of respondents thought that Clark should resign as B.C. Liberal leader if her party fails to form a government. Among B.C. Liberal voters, 46 percent think Clark should step down as leader if her party ends up sitting on the opposition side of the legislature.

A bare majority, 52 percent, expressed satisfaction with the first-past-the-post electoral system in B.C., in which single MLAs are elected in geographic constituencies. Almost two-thirds, 63 percent, think that any change in the electoral system should be approved in a referendum.

One of the B.C. Green party's demands for its support is to change the first-past-the-post system to an unnamed form of proportional representation. The B.C. Greens want this to be in place for the next election without holding a provincewide vote to gain citizens' consent.
