Today, the Prime Minister David Cameron gave a speech at easyJet's offices outlining why it could cost you and your family an extra £230 to go on holiday if we leave the European Union. Here's what he said.
"On the 23rd June we have got to make a really big decision for the future of our country... crucially I think we will be better off.
It is not a complicated argument to make. It is because we are part of a market of 500 million people, the biggest single market anywhere in the world. That is good for jobs, it is good for companies, good for investment.
It brings businesses here to Britain. It means great businesses like this one can expand throughout the single market. It is good for our economy, and so if we were to leave, it would be bad for our economy.
It would mean less growth, it would mean fewer jobs, it would mean higher price, it would mean as we set out yesterday, a recession for our economy, so we are better off if we stay in this organisation.
And it is not a static thing, because of course the single market is still expanding. It is good we have a single market in aviation, that has massively helped your business. I can remember the days, I am old enough to remember when flying off on holiday meant getting on a sort of state-owned aeroplane, and going to a state-owned airport in another country and paying a very high price for it.
As Carolyn said, prices have come down 40% since the single market has come about and since the radical transformation that companies like easyJet have brought about. So I am quite convinced that when it comes to this economic argument, we are better off if we stay in, and we are worse off if we leave.
As I have said it is not static because the single market is going to go into energy, it’s going to go into digital where we are a real leader, it’s going to go further into the services industry, which actually make up 80% of our economy. So for those reasons I think we will be better off.
And today we are talking about some quite specific things, some quite retail things, if you like, which is what would happen to the cost of a holiday if we were to leave.
If we were to leave, and the pound were to fall, which is what most people expect, and what the Treasury forecast, that would put up the cost of a typical holiday for a family of four, to a European destination, by £230.
It could, as Carolyn said put up actually the cost of air travel, because if you are outside the single market, which is what those who want us to leave think, then you would face all sorts of bureaucracy and restrictions that you don't face today.
We are establishing roaming charges, in the European Union. I mean, it is one of the most annoying things, you are on holiday, you use your mobile phone, you get an enormous bill. Getting rid of roaming charges could mean on a 10 minute call back to the UK, you are saving almost £4 on that 10 minute call.
I think there is very strong retail arguments about the cost of a holiday, the cost of food, the cost of using your phone, for staying in the European Union.
I think in this debate it is very important to talk about the specifics, and we have about jobs and prices and costs of holidays, and costs of phone calls, but there is also, in my view, a bigger argument. I don't believe those people who say, well, my head says we ought to stay in the European Union, but my heart says somehow, we would be a prouder and more patriotic country outside.
I don't think that is right. I think this is an amazing country, we are the fifth biggest economy in the world.
We have done great things in this world, we are a very interconnected country, what happens on the other side of the world matters to us, we care about tackling climate change, we care about trying to alleviate poverty in Africa, we know we need to have the world's trade lanes up for British business and enterprise.
I absolutely believe, if you want a big, bold, strong, United Kingdom, then you want to be in organisations like a reformed European Union, rather than outside them.
Britain is part of the G7, we are part of the G20, we are part of Nato, which helps to keep our defences strong, we are a very important part of the Commonwealth, which brings about a third of humanity together in one organisation.
And we are members of the European Union. Being in these organisations doesn't diminish our standing and our strength in the world, in my view it enhances it.
So I think the big bold patriotic case is to stay in a reformed European, to fight for the world we want, rather than to stand back, and be on the outside.
And in a way, that sort of what EasyJet has done. Here you are, a British based business, but a business that has decided to take on the world, in terms of being competitive, running routes all over Europe and beyond and recognising that is in your interests, your passengers' interest your shareholders interest. All the people in this rooms interest.
That is my argument about Britain.
Let us be the big bold strong Britain inside a reformed European, rather than voting to leave.
That is the case I am going to make every day between now and June 23rd, with just under a month to go."
