The Taoiseach, Brian Cowen, has said he is confident that a majority of Irish voters will support the Lisbon Treaty.
Mr Cowen was speaking today at Fianna Fáil's last major press conference before Thursday's referendum.
He said he believed there had been a swing to the 'yes' side in recent days following opinion polls predicting victory for the 'no' camp.
He also said he believed voters were seeing through the tactics of the 'no' campaign to create confusion about the treaty.
Sinn Féin president Gerry Adams, meanwhile, said today that the Government was lying when it said a better deal could not be negotiated.
Canvassing in Dublin city centre, Mr Adams said his experience in the Northern peace process taught him that there is always a Plan B.
