Last week Lynton Crosby and David Cameron briefed Conservative MPs on the threat posed by Ukip. Their timing was impeccable: today's YouGov poll showing 19 per cent of Conservative members would seriously consider voting for Nigel Farage's party could have sent Tory MPs into orbit, but instead they have been reassured that the party has a proper plan to deal with the enemies to the right, rather than the messy 'fruitcake' strategy of the past few years. I am told by a number of MPs who were present that Crosby talked generally about what attracts people to Ukip, rather than the specific problem of next year's European elections. This was based on polling the party has been carrying out.

It is interesting enough that Boris Johnson has attacked high-speed rail in today's Telegraph: the Mayor is undermining the priorities of the current government (while attacking Labour a little too), and reminding them that they are dithering on aviation policy. He warns that the project's costs will balloon to well over £70 billion. But the Mayor makes one very important comment about the government machine that should not go unnoticed. He writes: Talk to the big construction firms, and they will tell you the problem is not the cost of actually digging and tunnelling and putting in cables and tracks. Those are apparently roughly the same wherever you are in the world.

The funny thing about the new National Curriculum, published today, is that after all the fuss of the past few months, particularly over the history curriculum, it's probably the last ever national plan from the government. As more and more schools convert to academy status, and more free schools pop up to compete with poorly-performing schools, there will be fewer and fewer who must conform to this: the rest have been given freedom to teach what they judge is best for their pupils. Michael Gove's critics like to argue that he is a great centraliser, dictating the curriculum from Westminster while claiming to give schools freedom. But he only remains a centraliser where schools remain subject to centralisation and local authority control.

Ed Miliband's supporters have been arguing that he needs to show muscle on the Unite row before his opponents successfully argue that he is a weak leader in thrall to the union puppet masters. While Conservative MPs joked abut Tom Watson's 'Buddha' comments in the Chamber this morning, the Labour leader did speak out about Len McCluskey and the Falkirk row. To his credit, he has shown that muscle. He is referring the Falkirk allegations to the police this afternoon, and this morning, he said: We will act without fear or favour. Instead of defending what happened in Falkirk, Len McCluskey should be facing up to his responsibilities. He should not be defending the machine politics involving bad practice and malpractice that went on there, he should be facing up to it.

The Tory party have been having a very fun morning in the Chamber so far. The debate about James Wharton's Private Member's Bill for an EU referendum has had the atmosphere of a children's party. David Cameron was smiling on a frontbench like the indulgent father watching his child getting a little over-excited. William Hague played the part of conjurer, producing a magnificent speech attacking Labour and, to a lesser extent, the Lib Dems, for not giving voters a say.

It's eurosceptic party-time in Westminster today. Finally, the time has come for the Conservatives to show that they are the only ones who will #letbritaindecide. When I arrived in Parliament this morning, I was half-expecting a brass band and bunting to celebrate the momentous occasion of the second reading of James Wharton's Private Member's Bill, so excited are Tory MPs. But instead, CCHQ has placed digital posters at a number of sites across London, including the Vauxhall roundabout. You could be forgiven for thinking that the general election is this year, not 2015.
