French President Francois Hollande has paid his first visit to his partner Valerie Trierweiler since she was hospitalised in the wake of revelations he was having an affair.

Mr Hollande visited Ms Trierweiler at a Paris hospital yesterday evening, six days after she was admitted.

French magazine Closer reported last week that Mr Hollande was having an affair with French actress Julie Gayet.

Ms Gayet, 41, said yesterday that she plans to take legal action against the magazine for a breach of privacy.

She is seeking €50,000 in damages and €4,000 in legal costs from the magazine. If she wins, Closer will have to publish the legal verdict on its cover page.

At a press conference on Tuesday, Mr Hollande expressed his "total indignation" over Closer's publication of photos that the magazine said showed him and Ms Gayet arriving separately at a borrowed flat yards from the presidential Elysee Palace.

But the Socialist leader ruled out legal action on his own behalf, saying that would not be appropriate given that he enjoys immunity from any legal action.

His only comment about Ms Trierweiler was that she was "resting".

Even if Closer is forced to pay Ms Gayet the maximum amount she has claimed, the magazine's scoop should still be a money earner.

Earlier this week, it said it was on track to sell 600,000 copies of its edition with the Hollande/Gayet pictures, twice its usual circulation.

Mr Hollande was previously in a relationship with 2007 presidential candidate Ségolène Royal.
