Britain's Labour Party on Saturday announced Ed Miliband as its new leader Saturday, four months after Prime Minister Gordon Brown resigned from the post when his party lost the election.
Several rounds of voting were required to determine Saturday's winner, since no one received more than 50 percent support in the early ballots.
Ed Miliband and his brother, David, who was also in the running, were locked in a battle for the top spot for until the very end. The final numbers gave Ed 50.6 percent of the votes and David 49.35 percent.
"Today a new generation has stepped forward to change our party," Ed Miliband said upon the announcement. "We are united in our mission to transform Labour so that, once again, we stand up for the hardworking majority who play by the rules and want a less divided and more prosperous Britain. I know we have a lot of work to do. The journey starts today."
David Miliband served as foreign secretary under Brown. The Milibands faced competition from former Brown cabinet members Ed Balls and Andy Burnham, and London parliament member Diane Abbott.
Ed Miliband will now lead the opposition to the current coalition government, led by Prime Minister David Cameron, of the Conservative Party, and Deputy Prime Minister Nick Clegg, of the Liberal Democrats.
"I will oppose this coalition when it is doing the wrong thing, but I will support them when they are doing the right thing, and that is responsible politics and it the politics people in this country want," Miliband said.
