LONDON (AFP) - Britain's opposition Labour leader Ed Miliband is struggling to maintain the support of his centre-left party after just nine months in the job and his brother is waiting to take over, reports said Sunday. A YouGov poll for the Sunday Times revealed that more than half of Labour voters do not know what their party leader stands for and 41 percent said that electing him as leader had been the wrong decision. More than two thirds said he had been ineffective at providing opposition to Prime Minister David Cameron.
