Sinn Fein president Gerry Adams has called on disgruntled Fine Gael and Labour backbenchers to rebel over the Government's harsh austerity measures.
The Co Louth TD, who branded Public Expenditure Minister Brendan Howlin and Finance Minister Michael Noonan "Scrooge and Scrooger", said TDs need to take a stand against the unfair spending cuts and tax hikes.
"If they were just true to their election promises, they would have to vote against it," Mr Adams said. "If they were just keeping to the manifesto they were elected on, they would have to vote against it."
Mr Adams said he and his colleagues have spoken to a number of Fine Gael and Labour TDS over the last 24 hours, live on the airwaves, who have admitted they are dissatisfied with the direction the Budget has taken.
Labour veteran Tommy Broughan was kicked out of the party last week after he voted against the Government's decision to extend the controversial bank guarantee scheme. He became the third Government TD to leave his parliamentary position in just a matter of weeks.
Labour's Willie Penrose resigned from his post over the Government's decision to close Columb Army Barracks in Mullingar.
Denis Naughten was expelled from Fine Gael for refusing to support cutbacks in emergency services at Roscommon hospital.
Mr Adams also condemned Taoiseach Enda Kenny for supporting spending cuts and tax hikes that target normal Irish citizens, while lobbying for a pay rise for a special Government adviser.
"It's pitiable that working families, people under pressure, could lose up to 1,000 euro while the Taoiseach lobbies for a former Fine Gael adviser in the department of Richard Bruton to be given a 35,000 euro hike," he said.
"That is greater than the average wage. This notion of us all being together is a lie. It's a falsehood."
