Britain's former prime minister, Tony Blair, addresses Labour supporters and local business leaders during a visit to a public house in Denshaw, England, Tuesday May 4, 2010. Britain's main political parties crisscrossed the country to woo wavering voters Tuesday, but they also courted each other as opinion polls indicated that the national election could produce no clear winner. Back room deals may ultimately decide who governs Britain if all three main parties are denied an outright majority, as expected, in Thursday's vote. (AP Photo/Dave Thompson, Pool)
