The claim: The Treasury's analysis of costs and benefits of European membership says: “If we left the EU we’d have to re-negotiate trade deals with over 50 other countries.”
Reality Check verdict: Yes, the UK would have to renegotiate the current trade deals with non-EU countries. Some would be easier to secure than others.

The claim: "If EU countries were to offer the UK significant access to the Single Market, they would certainly insist that the UK accepts the associated obligations and rules, as every other country has had to do."
Reality Check verdict: We'd certainly be able to negotiate access to EU markets after Brexit, but it's hard to see other EU countries giving the UK a much better deal than everyone else.

The claim: In launching their analysis of the costs and benefits of EU membership, the Treasury said leaving the EU would cost families £4,300 per year by 2030.
Reality Check verdict: Families would not lose £4,300 per year if Britain left the EU.The Treasury model suggests that under one possible outcome of a Brexit, the UK's economy would be reduced by a sum equivalent to £4,300 for every household in the country by 2030. But that's not the same as saying it will cost every household that much.
Reality Check
Reality Check will be checking the Treasury analysis on the cost of an EU exit claim by claim today.
The report’s out shortly, but the Chancellor has trailed one finding already – that if the UK left the EU the cut in gross domestic product would be the equivalent of £4,300 for every household in the UK.
A couple of things to note. That's not the same as saying it would cost every household £4,300. A drop in GDP equivalent to £4,300 per household would be expected to cut household incomes, but not by that much.
They’ve used the same approach as the Centre for Economic Performance, and we’ve already explained the shortcomings in that method.
The other thing is that it’s based on the UK only being able to negotiate a trade deal like the one Canada has with the EU. That’s by no means the best case scenario.
If Britain were to negotiate a deal more like the one Norway has with the EU, the impact on the economy would be much less.
And as we’ve warned before, all economic modelling should be taken with a pinch of salt.

The claim: Migration from the EU has put huge pressure on public services, including the NHS. Boris Johnson, who's campaigning for Vote Leave, said: “We get uncontrolled immigration, which puts unsustainable pressure on our vital public services”
Reality Check verdict: There are no figures to show the exact cost to the NHS, but the 3 million EU citizens already here are likely to stay even if the UK leaves the EU.

The claim: Gisela Stuart, co-chair of Vote Leave, says: "Every week we send £350m to Brussels. I'd rather that we control how to spend that money, and if I had that control I would spend it on the NHS."
Reality Check verdict: Leaving the EU would not give the UK an extra £350m a week to spend on the NHS.

The claim: Jeremy Corbyn says: "The Labour Party's overwhelmingly for staying in", but Kate Hoey says that while MPs support Remain, the wider membership in in favour of Leave.
Reality Check verdict: We have all learned to be suspicious of polling data, but it seems Jeremy Corbyn is right that he leads a party whose members and supporters back Remain by a large margin.

The claim: "There are nearly three-quarters of a million British people living in Spain and over two million living in other parts of Europe."
Reality Check verdict: Wrong - the real figure for UK-born residents of Spain is 306,000, and for the EU as a whole is 1.2 million.

Reality Check verdict: The £850 figure confuses GDP per household with household income, and is based on economic modelling so needs to be taken with a pinch of salt.

Reality Check
The claim: Britain Stronger in Europe says 200,000 businesses trade with the EU while Vote Leave says 6% of UK firms export to the EU.
Reality Check verdict: These are only estimates, but one side or the other (or possibly both) is being overly conservative in making their claim. Reality Check applauds their caution.

The claim: "Voting to leave the EU risks the holiday pay of millions".
Reality Check verdict: Not likely - the UK had paid holiday before it joined the EU, and it would be politically dangerous to cut it back now.

Reality Check
The claim: The International Monetary Fund (IMF) says that the the referendum campaign has "already created uncertainty for investors" and partly blames recent falls in the pound on fears of a Brexit.
Reality Check verdict: It is likely to be one of the factors weakening the pound, but things like delayed interest rate rises are also responsible.

The claim: The EU has led the way on tax avoidance by coordinating the international drive to crack down on individuals and institutions who hide their money offshore.
Reality Check verdict: The EU has done some useful work on tax avoidance but cannot really be described as having led the way.

Reality Check
The claim: "The EU invests £11bn a year on manufacturing innovation programmes of which 15% are invested here in the UK."
Reality Check verdict: It's not £11bn a year, it's €11bn a year, but otherwise fair enough.

The claim: The UK leaving the European Union would mean an end to free emergency healthcare for UK tourists visiting EU countries.
Reality Check verdict: Not necessarily, the UK could agree reciprocal deals on emergency healthcare like the ones it already has with a number of non-EU countries around the world.

The claim: "Lord's Prayer - 66 words, 10 Commandments - 179 words, Gettysburg address - 286 words, EU regulations on the sale of cabbage - 26,911 words."
The verdict: Just under 2,000 words of regulations on the size and labelling of cabbages were repealed in 2009. Today there are no regulations specifically about cabbages.

The claim: David Cameron says: "We actually make more cars in the north east of our country - principally Nissan - than they do in the whole of Italy."
Reality Check verdict: Has been true in recent years but not any more - the latest figures suggest a turnaround in Italy in 2015.

The claim: John Caudwell says: "The immigration policy is set by the Europeans and not by the British", adding that the UK has no control over who other countries give passports to.
Reality Check verdict: He's overstating his case - it's true that Britain has to let EU citizens come to the UK, and that's part of the terms of membership of the EU. But Britain has complete control over immigration from outside the EU, and a say in the policies the EU develops.
