Yesterday the Prime Minister announced that the Eurozonehad to make-up or face a potential break up. His words seemed dramatic but today at a speech to business leaders inManchester, he's expected to repeat the sentiment. He'll say the Eurozone is at a crossroads.
It shows just how nervous the Government is that the crisis in Greece and the threat to the Eurozone could spread - affecting the UK too.
Britain's already in recession and yesterday the Governor of the Bank of England, Mervyn King, warned that what's happening in the Eurozone is threatening the UK economy and banking sector. The Eurozone is still Britain's biggest trading partner.
The problem is that David Cameron's on the sidelines looking in.
The UK is outside the single currency, has refused to pay towards an EU bailout fund and has little power to do anything but watch.
He knows though that he has to be seen to be doing something, even if that just means spelling out the fears of what happens if the Eurozone splits up. It will hurt.
