The Labour Party conference has voted overwhelmingly in favour of supporting the EU Constitution whenever the referendum is held.
Delegate Eoghan Beecher from UCC urged delegates to vote against it, because the party was telling them what to think, and because it facilitated privatisation and globalisation.
But MEP Proinsias de Rossa claimed the Constitution had left wing values, and was a 'slap in the face for Thatcherism'.
On RTÉ's This Week programme, Labour leader Pat Rabbitte said the conference's decision yesterday to seek a pre-election pact with Fine Gael has infused Irish politics with a 'new dynamic'.
He said Labour principles would not be compromised by any deal.
In his address to the conference yesterday, Pat Rabbitte ruled out tax increases for hard working families and said Labour would instead close off tax loopholes.
