Taoiseach Brian Cowen has stressed the importance of the Lisbon Treaty for the economy in the years ahead.
Mr Cowen was campaigning in Portlaoise as his party launched a new phase of its Yes campaign.
He urged voters to reflect on the importance of the Lisbon Treaty for the Irish economy.
Meanwhile Finance Minister Brian Lenihan has cautioned the campaign is far from over.
Speaking on RTÉ’s The Week in Politics Programme, Fine Gael TD Leo Varadkar warned that the Government's attitude towards his party could make it difficult for it to get a Yes vote in the Lisbon Treaty Referendum.
He was responding to a claim by Justice Minister Dermot Ahern that Fine Gael is opposed to everything since it lost last year's General Election.
‘We are campaigning very vigorously for a Yes vote in the Lisbon Treaty referendum and have been doing so since March. You had better acknowledge the work Fine Gael is doing in this regard and we are doing it very selflessly,' Mr Varadkar said.
‘And if Mr Cowen and people like you continue with your attitude, it is not going to help us get a Yes vote,’ he said
He urged Fine Gael supporters considering voting No, because they are angry with the Government, to hold fire until next year's local and European elections.
Yes campaign 'taking nothing for granted'
Earlier Minister for Foreign Affairs, Micheál Martin, welcomed the latest Red C poll results on the Lisbon Treaty, but added that the Yes campaign is taking nothing for granted.
The survey showed that 41% of respondents will vote Yes to the treaty - an increase of three points since the last Sunday Business Post poll a fortnight ago.
33% said they would vote No - an increase of five points, while the 'don't knows' have dropped eight points to 26%.
Minister Martin said he is 'very encouraged that the Yes vote is up in spite of the incredible barrage of aggressive attacks on the treaty launched in recent weeks'.
Libertas, which is campaigning against the treaty, said the findings showed that an intensive and expensive spending spree by supporters of the treaty had served only to narrow the gap between the two sides.
