Sunday's Greek election is a choice between staying in the euro and going back to the drachma, the leader of the centre-right New Democracy party has told a final campaign rally in Athens.

The general election, the second in six weeks, is seen as crucial to Greece's future in the eurozone.

New Democracy broadly accepts the EU/IMF bailout of debt-laden Greece but wants changes to the terms.

Main opponents Syriza reject the terms of the bailout but back the euro.

Syriza surged into second place on 6 May, in an election that produced an inconclusive result, with no party or coalition able to form a government.

Unofficial opinion polls suggest a fall in support for anti-bailout parties.

Under Greek election law, official opinion polls are banned in the two weeks before the election.
