French prime minister warns Valerie Trierweiler to 'keep to her place' It came amid reports Mr Hollande was furious at his girlfriend's 140-sign Twitter missive wishing "good luck" to Miss Royal's rival in the western La Rochelle constituency ahead of Sunday's elections. It put her at loggerheads with the president, who officially backs Miss Royal and has offered her a post as president of the National Assembly should she win. In more embarrassment for Mr Hollande, a poll released on Wednesday forecast Mr Falorni - who was expelled from the Socialist Party for refusing to stand down - will trounce Miss Royal by 58 per cent to 42 per cent on Sunday. While she narrowly came top in the first round, supporters of the local ousted Right-wing UMP candidate appear to be heeding his call to vote for "anyone but Royal." Meanwhile, Miss Trierweiler on Wednesday refused to apologise for the Tweet, saying it was "idiotic" to suggest she had acted out of jealousy of her boyfriend's former lover of 30 years. She told RTL radio: "To speak of jealousy in this business is idiotic. I see no mixing of public and private lives here. Things should be got back into perspective. Everything has got out of all proportion. But according to Le Parisien, Mr Hollande was furious at his girlfriend meddling in a parliamentary electoral campaign in which his party is heading for a majority. "The president was very angry," one Elysée aide told the daily. He took it really badly. He's a shy man. She overstepped the mark. This risks tainting his image.
