London ? Prime Minister Tony Blair’s government won a crucial parliamentary vote on sweeping new anti-terrorism legislation Wednesday, but faced a further fight over plans to lock up terrorist suspects for 90 days without charge.

Following a lengthy debate in the House of Commons, lawmakers voted 472-94 to back the Terror Bill.

The main opposition Conservative Party supported the bill, but warned it would seek to block the legislation at a later stage if the government did not rethink some of the proposals.

In the wake of July’s deadly attacks on London’s transit system, the government said it wanted to extend the maximum 14-day detention without charge for terrorist suspects to three months, outlaw attending terrorist training camps and make it an offense to glorify or encourage terrorism.
