Today in brief François Hollande warned that there would be ‘consequences’ for the British-French border deal that keeps migrants at Calais. Boris Johnson responded to the warnings that Brexit could lead to a ‘Jungle’ on UK soil with ‘Donnez-moi un break’. Jeremy Corbyn rejected the ‘failed economic orthodoxy’ espoused by the previous Labour government and called for a ‘new settlement with the corporate sector’. Caroline Lucas attacked Labour for its ‘silence’ in the EU referendum. Sajid Javid said he was still a ‘Brussels basher’ despite backing the campaign to stay in.

Tory MPs believe they have sufficient numbers of would-be rebels to be able to amend the government’s Investigatory Powers Bill, which was published yesterday. Coffee House understands that there are already around 10 Tory MPs who would be happy to join forces with Labour to change key sections of the legislation on the authorisation of interception warrants, and on the level of detail on someone's internet history that is available to intelligence services and the police. David Davis, the Tory MP who tends to lead the charge on civil liberties matters, is concerned that a number of the points set out by the joint committee that scrutinised the Bill when it was in draft form have still not been addressed now that it has been published.

Sir Jeremy Heywood is currently insisting to the Public Administration and Constitutional Affairs select committee that there is absolutely nothing untoward about his guidance to civil servants about withholding documents that have a bearing on the EU referendum from ministers. ‘I’m really struggling to see what the problem is here,’ he has just argued to MPs. The row is occupying the energy of an awful lot of Tory MPs at the moment, and is unlikely to go away. One way that ministers could escalate the dispute is to work with backbenchers and use departmental questions in the Commons to make their point about the impact that this guidance has on their ability to do their jobs from day to day.

Jeremy Corbyn’s much-awaited appearance at the weekly meeting of the parliamentary Labour party didn’t go particularly well this evening, which means that for the group of increasingly determined MPs trying to oust him, it was a hugely successful session. MPs were reminded that the meeting is off the record at the start, before being given a lecture by the leader about the importance of message discipline. They were told that there would be weekly messages that MPs should stick to. A number of MPs found this ‘unpalatable’, and some left.

The papers report today that many Conservatives are furious with the way David Cameron is conducting the referendum campaign. MPs threaten that if the Prime Minister continues with the personal attacks that he launched at various opponents on the 'Leave' side this week, it will impossible for him to continue at leader after the referendum, whatever the result. Today Iain Duncan Smith exacted some revenge on the Prime Minister with his own attacks on the Remain side, offering the Marr Show a rather furious critique of the campaign's tactics.

Jeremy Corbyn is this weekend campaigning against Labour Party policy. A year ago, it would have been quite unremarkable for the then obscure backbencher to turn up to the CND rally and give a speech against nuclear weapons. But now he's the Labour leader, Corbyn will be speaking against the current official policy of the party he heads up. This has obviously annoyed the many pro-Trident MPs in Labour, though some of their public frustration includes feigned surprise, given their party elected a man who sticks to his principles like glue, and who has hardly snuck those principles up on his party after election. He's been going on about them for years.

Quite naturally, those campaigning for Britain to leave the European Union have seized on today’s net migration figures as evidence that staying in won’t resolve voters’ concerns about immigration. Priti Patel has said that ‘the proposed deal will do nothing to reduce the level of immigration from the EU, and will leave unelected politicians in Brussels and judges from the EU court in control of our borders’. Liam Fox has decided to go further. He points out to Coffee House that it is impossible for David Cameron to both campaign for Britain to stay in the European Union and continue to commit to the net migration target - and that the Conservative party should drop that target.

Of all the publications from the Office for National Statistics this morning, the electoral statistics for the UK doesn’t sound like the most gripping. But it is the start of a very big political row, which is the boundary review. These electoral statistics will spark the formal review by the Boundary Commissions, which will then lead to new proposals for constituency boundaries later this year. Unsurprisingly, lots of MPs are nervous about this, especially Labour MPs who would face hostile constituency parties if they apply for selection in a new seat. The Labour whips alerted their MPs earlier this week, and are sending further updates once the Commissions make their announcements.

The number of Tory MPs who have yet to declare what their stance is in the EU referendum is dwindling. Some of those are away, including Tracey Crouch, who is on maternity leave and gave this very amusing response to those asking about her priorities, while others have decided not to reveal which way they will vote because they are holding public meetings between now and the vote, and want to stay neutral so that they can chair those. But some are either torn, or just trying to work out the best way of announcing their intentions. And for those MPs, the pressure is becoming rather more intense. Many were contacted by senior Tories, including George Osborne, last week in the run-up to David Cameron securing his deal (James has a very amusing detail on this in his magazine column).
