Greece's parliament approves plans for a controversial referendum on creditors' terms for a bailout, as the country faces a possible default.

The European Central Bank is expected to end emergency lending to Greece's banks on Sunday - a move that could lead to exit from the euro.

The European Central Bank says it will maintain its emergency funding of Greek banks at the level agreed on Friday.

Greek banks will be closed and capital controls imposed, the prime minister says, amid growing fears of a default and possible exit from the eurozone.
