The head of the European Commission Jean-Claude Juncker has said he feels "betrayed" by the "egotism" of Greece during negotiations over a new debt deal.

At a press conference, Mr Juncker said some of the Greek proposals were "delayed" or "deliberately altered". He said the Greek people "should be told the truth".

There was a glimmer of hope, however, with the EU boss saying that the door to talks was still open.

Negotiations between Greece and its European creditors collapsed over the weekend, resulting in Greek Prime Minister Alexis Tsipras calling a referendum on the issue and closing Greek banks for a week.

Mr Juncker said the talks were not "a game of liar's poker", stressing that "either all win or all lose".
