What do Rupert Murdoch and David Cameron have in common? They both love new Sun columnist Louise Mensch.

Former Tory MP Louise Mensch has replaced Toby Young as The Sun on Sunday's star political columnist (he's back to his brilliant blogging best at The Telegraph). The former Corby MP uses today's column to praise the Prime Minister's Europe speech:

"David Cameron played a blinder this week. His high-wire balancing act would have done credit to a circus. He managed to please Eurosceptics by offering them a referendum — and Europhiles by reassuring them that if we get what we want, he will campaign to stay in. For his flourishing finale, he even got Angela Merkel — head of the only country that really counts across the Channel in EU politics these days — to chime in and agree with him."

Number 10 will be delighted that Louise has got this spot. She might not be quite the loyalist that Nadine Dorries paints her - the Mid Beds MP Tweeted earlier this week that her former colleague would welcome the slaughter of the first-born if Cameron proposed it - but she is certainly a committed and I'd add principled Cameroon.

Louise used to write regularly for ConHome, starring as one of our former columnists. Her final column was a tribute to everything Margaret Thatcher stood for. My guess is that her place in The Sun is a little more lucrative!
