'Cameron is blackmailing like Thatcher'

French MP Alain Tourret has claimed that David Cameron has adopted "blackmail" tactics worthy of Margaret Thatcher.

Speaking during a gathering of the French parliament, Mr Tourret's comments were picked up by French broadcaster LCP.

That comment will surely please the eurosceptics...

Boris Johnson key to PM winning EU referendum

A new poll released this lunchtime suggests that Boris Johnson holds the key to David Cameron securing a victory in the EU referendum.

It comes after Mr Johnson attended 10 Downing Street this morning for 40 minutes of talks with the Prime Minister, but he left saying: "I'll be back. No deal."

One in three people told pollsters Ipsos MORI that the Mayor of London will be "important" to them when deciding which way to vote.

The survey for the Evening Standard also found that the "remain" campaign is 15 points ahead.

Mr Cameron and Mr Johnson jointly supporting Britain's membership would convince many of staying. But if they are at loggerheads over our membership, the pair will cancel each other out, according to the research.

Mr Johnson's opinion was only second to that of the Prime Minister, with 32 per cent saying it was important to them, compared to the PM's 44 per cent.

Nigel Farage, the Ukip leader, mattered to only 20 per cent of those surveyed.

Britain's world influence 'limited' if it quits EU

Steven Swinford, our Deputy Political Editor, writes

Britain's international influence will be "significantly limited" if it leaves the European Union, peers have warned.

A House of Lords report said that the EU has "glaring weaknesses" in its strategies for dealing with "unstable and dangerous neighbours".

It said that Brussels was "unprepared" for the increased terror threat and the refugee crisis and claimed the 28-member bloc's approach to Turkey is in "disarray" and called for an urgent policy review.

However the EU sub-committee on external affairs also warned Britain standing in the world will be significantly reduced if it quits the EU.

Committee chairman Lord Tugendhat said: "We believe the EU faces a further test should the UK decide to leave the EU.

"If this were to happen, the UK's international reach would be significantly limited because it would not have access to Commission instruments. In turn, the EU's foreign policy would carry less weight.

"Although there have been some EU foreign policy successes, notably the nuclear deal with Iran and maintaining effective sanctions on Russia, we believe that there is much room for improvement on how the EU's foreign and security policy operates."

Confusion over Turkey's future as an EU state must be resolved because of the state's role as a "critical buffer state" in the refugee crisis and the fight against Islamic State, peers said.

Britain's aspirations are 'non-starters' in EU deal

Michael Fabricant, the Tory MP for Lichfield, has tweeted me to say that Britain's "achievable" aspirations in the EU were not demanded in the first place, adding that they would have been "non-starters" in the negotiations.

So, I asked him, if David Cameron's deal is trimmed back further by EU leaders this week, what does that leave him with? Not much it seems.

How the next 72 hours will unfold

The plan could change, but under one timetable being prepared, the leaders will arrive in Brussels on Thursday afternoon, and after press interviews and a group photograph talks on Britain's deal are expected to begin at around 5pm. Over dinner, at about 8pm, leaders will turn to the migration crisis.

Then Donald Tusk - who normally insists on summits ending at midnight - is expected to take leaders aside in turn in the hope of wearing down their objections and presenting an accord early on Friday morning.

That will allow Mr Cameron to address his Cabinet that afternoon, triggering a four-month referendum campaign.
