David Cameron's plan for this autumn was to largely avoid the topic of Europe at his party's conference, then to focus on the issue later in the year. It's only a few days since the Tories gathered in Birmingham, and the Prime Minister is already facing a big week on Europe. Home Secretary Theresa May will kick things off by announcing today that she wants Britain to opt out of more than 130 European Union measures on law and order, including the European Arrest Warrant. The opt-out itself, which the Home Secretary is expected to say Britain is 'minded' to do, is not the tricky bit: it's which measures to then opt back into.

The Conservative party conference has been short and sweet, and delegates are winding their ways back to constituencies and Westminster. Here are five important lessons to take away from Birmingham: 1. The government will pursue a further cuts to the welfare budget, but there's a fight ahead on how much money can be cut, with the Liberal Democrats rejecting the George Osborne and Iain Duncan Smith's plan for £10 billion of cuts. James examines how the relationship between Osborne and Vince Cable will be key to the negotiations over further cuts in his political column in tomorrow's Spectator. 2. David Cameron is keen to keep both compassionate Conservatism and the Big Society alive as key brands for the Conservative party.

David Cameron's speech today to the Conservative party conference will be deeply personal, and deeply challenging. I understand that the Prime Minister is going to weave in stories from his own life: pushing his late son around in his wheelchair, and his late father's own story. He will say: 'It’s only when your dad’s gone that you realise – not just how much you really miss them – but how much you really owe them. My dad influenced me much more than I ever thought.' These this-is-who-I-am details will help the Prime Minister talk about his vision for the Conservative party, and his vision for the country too. It's not dissimilar to the approach Ed Miliband took in his own speech last week.

I had the pleasure of chairing a fringe event hosted by the Howard League for Penal Reform today on young people and the criminal justice system. The focus for the event was how police and crime commissioners can change the way young offenders are treated. Home Office minister James Brokenshire was very keen to assert that PCCs should be 'ambitious' in their plans for dealing with young people. But Home Affairs Select Committee member James Clappison was a little less optimistic, particularly about whether the government is actually pushing hard enough for these commissioners to be a momentous change to policing.

Nick Boles started his first fringe as a minister this evening by saying that after years of trying to make controversial points at party conference events, he wasn't going to say anything interesting. The new planning minister's attempt at being boring wasn't thoroughly successful: Boles' version of being dull and unreportable is still more fascinating than some politicians will ever manage. He opened his speech to the IPPR event by praising the good intentions of the Labour government in building more homes. But there was one fatal flaw in that plan, he said: 'The last government had many good intentions in this area. They made life a lot more difficult for themselves in combining their desire to build more housing with their desire to completely open borders and open immigration.

David Cameron has a tough task ahead of him for this week's Conservative conference - a task that got a little harder when Ed Miliband surprised almost everyone by producing a cracking speech this week. The Prime Minister has a number of problems to tackle when he arrives in Birmingham. These include a rowdy party growing increasingly agitated about a number of issues including Europe, a chief whip sent in to control said rowdy party whose authority has been undermined before he has even started twisting arms, a chancellor struggling with his own authority on economic policy, and a Mayor determined to steal the show with his own conference speech and his building campaign against Heathrow expansion.

Believe it or not, Labour's party conference has finally ground to a halt. Here are the key lessons from the past six days in Manchester: 1. Ed Miliband is no longer a joke leader of the opposition. The Labour leader's speech showed that he can now talk a good game, and even though much of that performance was no more than a good game, Miliband gave his party and voters a glimpse of the more authoritative figure that he has grown into over the past two years. It's worth watching his speech to the 2010 autumn conference where he appeared completely floored by bursts of applause to see quite how far he has come. 2.
