Valerie Trierweiler, French first lady, is in hospital

French First Lady Valerie Trierweiler has been admitted to hospital after media reports of an alleged affair involving President Francois Hollande and another woman.

Her office said she had been admitted on Friday "for rest and some tests".

Mr Hollande's unmarried partner was admitted a day after Closer magazine published images of the alleged affair.

The French leader has not denied secretly visiting actress Julie Gayet at a flat near the Elysee Palace but protested at invasion of his privacy.
