France's Sarkozy announces return to politics
The announcement on his Facebook page ends months of local media speculation that the 59-year-old conservative would return to the fray after his defeat by Socialist Francois Hollande in 2012.
"I am a candidate for the presidency of my political family," he said.
A divisive figure reviled by many left-wing voters, Sarkozy is seen by his supporters as the only politician capable of rallying the fractured centre-right UMP party to a victory in 2017. But any political comeback could be tripped up by a series of legal troubles hanging over his head.
