A group of Irish deputies have made a fresh bid to delay the EU Fiscal Treaty Referendum – as pressure grows on the single European currency.

The Euro sank to a four month low against the dollar on Thursday morning as a Greek exit loomed closer.

The failure to elect a new government in Athens has raised serious question marks around the future of the Euro.

And the latest opinion polls in Ireland suggest Prime Minister Enda Kenny has a real fight on his hands to win the referendum with a third of voters still undecided on how they will vote.

The No camp is currently outnumbered 3 to 2 amongst those who know how they will vote according to the latest opinion poll for the Irish Independent.

But opponents of the Treaty believe the problems in Greece should justify a postponement of the referendum, set to be held at the end of the month.

Independent deputy Shane Ross is now tabling a parliamentary motion to delay the vote as Kenny faces up to the latest opinion poll results.

With two weeks to go to polling, the Irish Independent-Millward Brown Lansdowne opinion poll shows the Yes side has a commanding lead.

But the paper reports that more than one-in-three voters are still unsure how they will cast their vote.

The Independent poll, conducted earlier this week, shows 37 per cent saying they will vote Yes, with 24 per cent in the No camp. But 35 per cent of voters say they still don’t know how they will vote, while just 4 per cent say they won’t vote.

When the don’t knows are excluded, it is 60 per cent Yes compared with 40 per cent No.

The poll also shows Irish voters want to stay in the eurozone with three out of every four voters infavour.
