French President Francois Hollande has confirmed his separation from his partner Valerie Trierweiler.
He told the French news agency AFP that their "shared life" had ended.
Two weeks ago a magazine published photos which appeared to show Mr Hollande had been having an affair with an actress, Julie Gayet.
Ms Trierweiler spent a week in hospital after the revelations.
Mr Hollande, who has never denied having an affair with Julie Gayet, has admitted to a "difficult moment" in his relationship with Ms Trierweiler.
As a self-acknowledged cheater. Should he resign?
Thus ends a remarkable emotional saga that has captivated the French - and the world - for the last two weeks. It was probably inevitable that it would end like this, with Valerie Trierweiler quitting the Elysee.
But the lack of any official communication had given rise to all sorts of rumours. Right until Francois Hollande came out with his personal statement breaking their relationship, it was impossible to rule out a reconciliation.
What happens now? Well, the president has not said it publicly, but his entourage have passed on the message: for the time being there will be no replacement for the ex-first lady. Indeed, Mr Hollande is said to regret ever elevating Ms Trierweiler to the position in the first place, as her unease in the role clearly posed problems from the start.
As for Julie Gayet, we shall have to see how he continues his relationship with her. Maybe she will become an acknowledged part of his life, but without any official role and certainly not moving into the Elysee. Perhaps at some point she will start being seen with him, and accompanying him on trips.
But probably that won't be any time soon. Right now the president would probably prefer some time tangle-free.
At the time, he promised to clarify the situation before his official visit to Washington on 11 February.
Mr Hollande told AFP he was speaking in a personal capacity and not as the head of state.
"I am making it known that I have put an end to my shared life with Valerie Trierweiler," he said
