The last major opinion poll of the Lisbon Referendum shows growing support for the Treaty with just six days to go to polling day.

The Red C poll in tomorrow's Sunday Business Post shows that, excluding those who have yet to decide, the Yes lead has stretched to more than two-thirds of voters.

More than 1,000 voters around the country were surveyed on Monday, Tuesday and Wednesday.

The results show that 55% of adults said they would vote Yes, up one point since the last poll two weeks ago.

27% said they would vote No, up two points and 18% are undecided.

When the 'undecideds' are excluded, the Yes side leads by 67% to 33%.

The Taoiseach has said that supporting the referendum and showing Ireland's commitment to Europe is one of the stepping stones to effecting economic recovery sooner rather than later.

Fine Gael leader Enda Kenny has said people should put the country first by voting in favour of the Lisbon Treaty.

Launching another poster campaign for a Yes vote, Mr Kenny said passing the treaty would see Ireland gain in stature and gain in strength.

He said the Irish people now had a chance to be at the forefront of, and benefit from, change and progress in Europe.

Meanwhile, Patricia McKenna of the People's Movement has said she believes there is great momentum building up on the No side as election day gets closer.

She said indications that No voters were growing in number was a sign that change was afoot and that people were starting to think carefully about ‘the so-called promise of jobs and threats of isolation in Europe.’
