A new poll suggests that a modified version of the Lisbon Treaty would be carried if certain concessions are made to Ireland.

The TNS/mrbi poll in tomorrow’s Irish Times asked voters if they would they vote Yes or No in another referendum if the Treaty was modified to allow Ireland retain its EU Commissioner and if concerns on neutrality, abortion and taxation were clarified in special declarations.

The result was 43% said Yes; 39% said No and 19% said they did not know.

When the ‘Don't Knows’ are eliminated the result gives a slightly bigger margin to supporters of the Treaty.

The Yes vote without the ‘Don't Knows’ is 52.5% with 47.5% for the No vote.

In the referendum last June, 53.4% voted to reject the treaty, while 46.6% voted in favour.

December decision on Lisbon referendum

The Government will make its decision on whether to hold another referendum on the Lisbon Treaty before the European Council meeting in December.

Minister for Foreign Affairs Micheál Martin told RTE's ‘The Week in Politics’ that the decision has not been made yet.

He said the Government will bring the ‘elements of a solution’ to the meeting in Brussels next month.

Mr Martin said the Government wanted to restore the goodwill Ireland had built up in the EU over many years, because this would enable the country to play a part in future decisions.

When asked if the Government would hold another referendum if it got the necessary assurances it wanted, Mr Martin said: ‘The Government will make that decision in advance of the December meeting.

'We haven't made that decision as of now and I mean we have looked at a variety of alternatives, and we have also consulted with our political parties here at home’.

The Minister said that doing nothing would leave Ireland at the margins of Europe.

‘We want to be at the heart of European decision making,’ he said.

‘That would enable us to have some impact on decisions into the future and that would strengthen our hand in negotiations on agriculture and budgets and so forth.’
