Furious opposition MPs accused Prime Minister Stephen Harper of muzzling the House of Commons after he moved for the second time in a little more than a year to suspend Parliament. Mired in controversy over an alleged cover-up on the torture of Afghan prisoners and eager to increase the Conservatives' power in the Senate, the government is closing down Parliament until March 3, the Prime Minister's Office said Wednesday. The decision is about one thing and one thing only - avoiding the scrutiny of Parliament at a time when this government is facing tough questions about their conduct in covering up the detainee scandal," Liberal Leader Michael Ignatieff said in a statement. "Mr. Harper is showing his disregard for the democratic institutions of our country." Harper spoke Wednesday by telephone with Governor-General Michalle Jean, who agreed to the suspension. The prorogation of Parliament until after the Winter Olympics in Vancouver will likely scuttle dozens of pieces of legislation, and give the Tories a chance to increase their representation on Senate committees. The government has been on the defensive for weeks over allegations it failed to act on information that prisoners being passed to Afghan authorities by Canadian soldiers were at risk of being tortured.
