Ministers are 'taking steps' to protect Britain from economic turbulence in the eurozone amid fears Greece is on the cusp of crashing out of the single currency after its pleas for a bailout extension were refused. Chancellor George Osborne was briefed as eurozone finance ministers meeting in Brussels refused to extend the financial assistance package in place to help the failing economy. It will end as planned on Tuesday - the day Greece must make a debt repayment of €1.6billion (£1.1billion) to the International Monetary Fund that it cannot afford. Eurozone ministers also criticised Greek prime minister Alexis Tsipras for announcing that a snap referendum on bailout proposals will be staged next week.George Osborne briefed over impact Grexit would have on BritainComes as Brussels refuses to extend financial assistance packageGreek PM announced a snap referendum of bailout proposals next week
