Greek voters in favour of creditors’ proposals were marginally ahead by 0.6 points to those poised to reject them in Sunday’s referendum, an opinion poll published on the Web site of Proto Thema had said on Friday.

The survey by Alco pollsters on behalf of the newspaper said 41.7 per cent of respondents would vote ‘Yes’ on Sunday, 41.1 per cent would vote ‘No’ and 10.7 per cent were undecided, Proto Thema said.
