The Taoiseach and the Minister for Foreign Affairs have been accused of "duplicity" over a possible war against Iraq.
Speaking at a press conference in advance of Saturday's anti-war demonstration, Dr Jerry Cowley, Independent TD for Mayo, also questioned the support being given to the United States by the Government.
He said the US was "obviously" gearing for war and that the Irish people are being given a version of events that is "simply not true."
Dr Cowley said it was time to demonstrate opposition to war by lobbying the US embassy and the British embassy as there was "no point in being opposed to the war unless you say it".
Dr Cowley was speaking at a press conference organised by the Peace and Neutrality Alliance that was also attended by a number of TDs who have voiced opposition to a possible war on Iraq.
Joe Higgins, Socialist TD for Dublin West, claimed the US and British governments were "cultivating hysteria with overblown terror alerts".
He said war was imminent "with or without" a United Nations resolution and that the Irish Government "debases itself" in its subservience to US foreign policy and that their recent statements were "merely a parroting of the arguments of the Bush and Blair axis".
He said the Government was refusing to give its position in "the likely event" of a unilateral attack on Iraq.
This morning's press conference was the final conference before Saturday's march. It was organised to give a platform to Independent TDs who have voiced opposition to the war. Those present included Mr Finian McGrath (Dublin North Central), Mr Seamus Healy (Tipperary South), Ms Marian Harkin (Sligo-Leitrim) and Mr Tony Gregory (Dublin Central).
Organisers of Saturday's march are expecting between fifteen to twenty thousand people to attend the march in Dublin. The event is being held as part of a worldwide day of action which was first suggested at
