British Prime Minister David Cameron has called on European leaders to sort out the present crisis in the eurozone.

Addressing business leaders, Cameron pledged to do whatever is necessary to protect Britain's economy and financial institutions from a break-up of the eurozone.

British Prime Minister David Cameron said, "The euro zone is at a crossroads. It either has to make up or it is looking at a potential break-up.

Either Europe has a successful, committed euro zone with an effective firewall, well-capitalised and effective banks, a system of fiscal burden sharing, a supported monetary policy across the euro zone or we are in uncharted territory which carries huge risks for everybody. As I have consistently said, it is in Britain's interest for the euro zone to sort out its problems."
