Rebels force German presidential vote to 3rd round
Rebel votes among the ruling centre-right coalition meant Christian Wulff, state premier of Lower Saxony, failed in two rounds to beat the centre-left's candidate Joachim Gauck, a Protestant pastor and civil rights campaigner.
In the third round, to be held shortly, candidates need only a simple majority to win. Merkel badly needed a clear victory to offset criticism of her leadership in the financial crisis and record low standing in opinion polls.
