Greek Prime Minister Alexis Tsipras said in a speech on Wednesday that Greeks should vote "no" in Sunday's referendum. He added that "no" would not mean that Greece have to leave the Eurozone.

Tsipras reassured Greeks that their deposits were safe.

He also said that he would continue to negotiate with the country's lenders.

Earlier, Greek prime minister signalled that he was ready to accept the most spending cuts demanded by the country's creditors.
