OTTAWA - The NDP is urging the governing Liberals to surrender majority control over the special Commons committee that's supposed to recommend an alternative to Canada's first-past-the-post electoral system.

Nathan Cullen, the NDP's democratic reform critic, says membership on the promised committee should include all parties that won seats in the House of Commons in last October's election and be proportional to each party's share of the popular vote.

That would mean five Liberal MPs, three Conservatives, two New Democrats, one Bloc Quebecois and one Green party member.

As the governing party, the Liberals are ordinarily entitled to majority membership on Commons committees; the Bloc and Greens are not entitled to any members because they didn't elect enough MPs to qualify for recognition as a party in the House.

But when it comes to something as fundamental as electoral reform, Cullen says no one party should have the power to unilaterally change the foundation of the country's democratic institutions.

Moreover, he says, electoral reform should be driven by the will of Canadians and that would be better reflected through proportional representation on the committee.
