Three people familiar with discussions currently taking place between Greece and its creditors in the 19-country eurozone say new Greek Finance Minister Euclid Tsakalotos has not presented fresh written proposals over how to win support for a financial bailout.

The three eurozone sources, who spoke on condition of anonymity because of the sensitivity of the negotiations, said Tsakalotos gave an oral update of the financial situation in Greece instead. He had been widely tipped to present reform proposals in written form.

No further details were available.

Prime Minister Alexis Tsipras is expected to arrive at an emergency summit of eurozone leaders later as his country struggles to forge a bailout deal that would ease the pressure on the country's shuttered banks and prevent a Greek exit from the euro.
