Voting is underway in Britain's general elections with Prime Minister Tony Blair and his Labor party headed for a record third consecutive term. But last minute polls indicate that lingering discontent over the war in Iraq could diminish Labor's parliamentary majority. Analysts say turnout could be crucial to the result. The polls indicate that main opposition leader Michael Howard and his Conservative party failed to make progress on Labor during the month long campaign. The polls also suggest the anti-war Liberal-Democrats could benefit from discontent over Mr. Blair's support for the Iraq war -- which may reduce Labor's commanding majority in the 646-seat House of Commons. The prime minister has focused much of his campaign on Britain's robust economy, while the Conservatives concentrated on issues like public services and immigration.
