A French court has ruled investigators can retain the seized diaries of ex-President Nicolas Sarkozy, who is battling corruption allegations, reports the BBC.
The Court of Cassation rejected Mr Sarkozy's challenge to the seizure.
The diaries were initially confiscated as part of an inquiry into alleged illegal funding during his successful 2007 presidential campaign.
That case has since been dropped, but the diaries may be used in other investigations targeting Mr Sarkozy.
The former president, who lost his re-election bid in 2012, is planning a political comeback and correspondents say the drip of allegations has harmed him.
The diaries were seized after claims surfaced in 2010 that Mr Sarkozy had taken advantage of 90-year-old L'Oreal heiress Liliane Bettencourt when he was standing for president.
It was alleged that Mrs Bettencourt had given large sums of cash to Mr Sarkozy's aides. Both Mr Sarkozy and Mrs Bettencourt denied this. Last October, Mr Sarkozy was removed from the list of defendants.
