British regulators are meeting with banks to discuss the state of their preparedness for a potential breakup of the eurozone, according to people familiar with the matter.

The UK's Financial Services Authority has been talking with chief risk officers at top British and international banks to get a better understanding of their contingency planning, the people said. The regulator has asked banks to submit reports detailing their preparations for what would happen if the monetary union unravelled or if individual member countries were to revert back to their old national currencies.
