Greece Prime Minister Alexis Tsipras will meet with German Chancellor Angela Merkel today (Monday) as new fears grow over Greece's debt problem.

The two have been disputing the prospect of additional aid for months, with Germany holding out for economic reforms in Greece as some form of insurance policy.

Mr Tsipras is expected to explain that Greece will not be able to meet its upcoming repayment deadlines without more aid.

On Friday, Ms Merkel said there would be no more aid until economic reforms are implemented - a position backed by Spain's Economy Minister, Luis de Guindos.

In a letter to Ms Merkel on 15 March, the Greek Prime Minister is understood to have told his German counterpart that he may have to choose between paying pensions and wages, and making repayments on its huge debt.
