Sinn Fein leader Gerry Adams has called on the Labour Party to collapse the Irish government.
At his party's ard fheis (annual conference), he ratcheted up an ongoing onslaught on the junior coalition partners.
Evoking Labour's founding fathers James Connolly and Jim Larkin, Mr Adams said a real Labour party with a principled leadership should not be administering power with Fine Gael.
"Stand by working people as Connolly and Larkin did," he said.
"Leave this government and leave it now."
The Louth TD used his keynote address at the gathering of the party faithful in Castlebar, Co Mayo - home to Taoiseach Enda Kenny - to attack austerity, target rural voters and urge more work on the Peace Process.
Turning his attention to the Republic, he said the current Fine Gael/Labour coalition had failed the Irish people by implementing core values of austerity.
Mr Adams singled out the handling of the banking crisis, selling off of natural resources and the controversy over public sector pay cutbacks.
While the government was willing to cut child benefit, carers allowances and home-help hours, it had no problem putting taxpayers money into the pockets of bankers and financiers, he told delegates.
Mr Adams said there are cuts to hospitals, schools and garda stations alongside taxes on pensions, savings and homes, but he insisted bankers, developers and politicians who created the mess have been untouched.
