Diary: Obsessed by gay marriage? Look who's talking, David Davies

David Davies, MP for Monmouth: 'David Cameron needs to change his tack very rapidly, otherwise he’s not going to be in position for very long' (PA)

Another Tory MP has followed the intrepid Nadine Dorries in warning David Cameron that he is in danger of the sack. David Davies, MP for Monmouth (not to be confused with the better known former minister David Davis), has told his local newspaper, the South Wales Argus: "David Cameron needs to change his tack very rapidly, otherwise he's not going to be in position for very long."

He also wrote a letter for publication in the same paper that said: "May I also offer my apologies to those who feel the Conservative-led Coalition has let them down. I must acknowledge there has been incompetence at the highest levels of government over the last few months in a number of departments.

"Meanwhile, there has been an emphasis on issues such as gay marriage and reform of the House of Lords, at the expense of explaining the financial situation; a failure to deport dangerous terrorists because of concerns about human rights; and an apparent unwillingness to listen to the concerns of electors."

Far be it from me to fight David Cameron's corner for him, but he has hardly put an "emphasis" on gay marriage. He defended his belief in it in his speech to the annual party conference in October, and in April he told church leaders that he did not want to fall out with them over it. If he has said anything else about it in public in the past 12 months, I confess I missed it.

Mr Davies, on the other hand, has nothing on the home page of his website about the economy, but a whole page of the site is devoted to explaining his opposition to gay marriage. Which just goes to show that the people most obsessed by gay marriage are those who oppose it.

British boldness rubs off on Obama

Barack Obama's decision to back gay marriage puts a story from David Cameron's visit to Washington in a new light. As Mr Cameron waited to step out on to the White House lawn with the President, a guest told him how much he admired him for daring to speak out on gay marriage at all, almost as if he was hoping some of the boldness of the British Prime Minister would rub off on the President. Now it has.

The madness of the Mogg

Jacob Rees-Mogg is another Tory MP on a mission to pull his party to the right. Last night he called for a return to "full-blooded Toryism", which would include making no further financial contributions to the EU, cancelling all foreign aid, and ending the commitment to reducing carbon emissions – a proposition encapsulated in the slogan "put people before polar bears". The Mogg is an articulate advocate of the free market, and I would not want to indulge in the floccinaucinihilipilification of his opinions, but his proposals are hardly realistic for a party that has not won a general election for 20 years.

A Lying B'stard for every city?

Oh dear. The only success last week for David Cameron's campaign to have a "Boris in every city" was when the good people of Bristol voted Yes to a directly elected mayor, when everywhere else they were voting no. Now Eric Mutch, a Bristol café worker, is threatening to reduce the election to a farce. He has announced that he is putting himself forward as a candidate, after changing his name by deed poll to "Mr Corrupt Self-serving Lying B'stard".
