Fianna Fáil leader Michael Martin says the coalition parties are obsessed with their positioning on the political landscape, rather than developing a vision for the future.
Speaking at the annual Fianna Fáil President's dinner, Mr Martin also attacked Taoiseach Enda Kenny over the Seanad referendum, saying the people "expect their leaders to be willing to debate" .
Mr Martin joked that in October four years ago Mr Kenny went to his party’s annual dinner and "decided that he needed to pull a rabbit out of a hat – and that rabbit was Seanad abolition".
"Let me tell you, given what happened today I’m not going to copy him tonight," he added.
Mr Martin said the Government thought no one would take the time to look beyond their slogans and attacks in the referendum campaign.
"Today they have been proven wrong. The Irish people said No to the power grab, they said they want real political reform not just empty spin about reform.
"They also said that they expect their leaders to be willing to debate," he said.
"When the referendum proposal was published in the summer the polls predicted a 74pc yes vote. The government saw these figures and decided to rush the campaign and limit debate. Sinn Fein saw these figures and decided to switch sides even though their leader compared the proposal to a coup d’état.
"We saw those figures and decided to stand by the principle that we want real reform of Irish politics," he added.
"Fine Gael has taken a marked move to the right. In the last two budgets its policies were deliberately skewed to putting the biggest impact of spending cuts and tax increases on struggling parts of our society.
"It is also the party which is working to change as little as possible in how Ireland is governed. It talks the talk of change, but its conservative and reactionary core is stronger than it’s ever been," he said.
"As we’ve seen in the last week the Labour Party’s primary concern is the Labour Party. They’ve spent more time talking about what posters are in Joan Burton’s shed than their growing list of broken promises.
"Two and a half years away from an election they are in crisis not because of the deeply unfair budgets they delivered or the broken promises on education, health and welfare they enacted – but because they think they might lose lots of seats.
"Labour and Fine Gael’s policy on the North is to neglect it until it becomes a crisis and on Europe it is to wait for things to happen which they think they might be able to claim credit for.
"There is no attempt to set out a vision for our future. There is no sense of what sort of Ireland they want us to be in five or ten years’ time other than the fact that they want to be in government," he said.
Mr Kenny said the defining characteristic of this Government is that it sees Ireland’s problems solely through political eyes.
"For them the spin comes first and the substance is an afterthought. They spend their time trying to refight the last election and waiting for developments which they can try to claim credit for," he said.
