Chancellor George Osborne will issue a warning on the need for the European Union to reform during a keynote address later today.
The Chancellor will stress the Conservatives' determination to renegotiate the terms of Britain's membership, declaring "We can't go on like this." Addressing a conference on EU reform, he will say:
"The biggest economic risk facing Europe doesn't come from those who want reform and renegotiation - it comes from a failure to reform and renegotiate.
"It is the status quo which condemns the people of Europe to an ongoing economic crisis and continuing decline. And so there is a simple choice for Europe: reform or decline.
"Our determination is clear: to deliver the reform, and then let the people decide."
