1. UK Chancellor George Osborne and Labour party politician Alistair Darling arriving at news conference
2. SOUNDBITE (English) George Osborne, UK's Chancellor of the Exchequer:
"Let's take the mid range of what the impeccably independent Institute for Fiscal Studies says there would be in terms of a black hole in the public finances. The mid range, not the worst case, the mid range, is a 30 billion pound (42.4 billion US dollars) hole in the public finances. This would be a permanent and structural hole. We couldn't just borrow more money to tide ourselves over."

4. SOUNDBITE (English) George Osborne, UK's Chancellor of the Exchequer:
"And this is just the hard reality, we've both (referring to former Chancellor Alistair Darling) been there in the chair, you've got to make the books add up, and frankly, there are only a certain number of taxes you can put out that are going to raise the sums required and there are only a certain number of big government budgets you can cut, and that's the cold reality of quitting the EU."
5. Osborne and Darling listening to audience
6.SOUNDBITE (English) George Osborne, UK's Chancellor of the Exchequer:
"A vote to remain is a vote for a strong economy. With all my heart, I will be fighting every hour until next Thursday to persuade people that we are stronger, safer and better off by voting to stay in a reformed EU."

8. SOUNDBITE (English) Alistair Darling, Labour party politician and former Chancellor of the Exchequer:
"Here we are, six years after the (2008) banking crash, and the economy is growing, but we know the rest of the world is still in a fairly fragile state. Why on earth would we leave the largest single market we have, the largest one in the world, when we know there's going to be a hit, when we have no idea what the future holds, it's a leap in the dark, and when we know the consequence of doing that. The Chancellor couldn't leave it for several years before he got around to doing something about it, he'd have to sort it out now, which is why both of us are saying, with my experience eight years ago, George Osborne with experience now, we'd have to do something about it now. And that something is something we'd both like to avoid, we don't need to do it, it would be a self-inflicted wound."

10. SOUNDBITE (English) Alistair Darling, Labour party politician and former Chancellor of the Exchequer:
"This country next week is going to take a massive decision. A decision on which we can't go back. And if we do that, the risk is that we get ourselves into even deeper water because we're coming to it from a low base. Which is why I think it's absolute madness for us to take a leap in the dark, into a position where we can't come back. And that's why I think people should think long and hard about this, and just think about the risks as well as the gains if we remain in the European Union."
