A former Fine Gael MEP has said the Taoiseach needs to refocus his leadership of the party to ensure a slide in support is arrested before the next General Election.
Jim Higgins said Enda Kenny was "whistling past the graveyard" and that he should sack his advisers and rely on his political instincts to govern.
Mr Higgins lost his seat in the European Parliament last May.
In an interview in today's Western People newspaper in Co Mayo, he said a drastic reappraisal of party strategy was needed if Fine Gael wished to secure a second term in office.
He said the organisation was falling apart and that long-serving members were disillusioned.
Mr Higgins said shrewd political management was now needed.
Earlier, Mr Kenny said it is the Government's intention to serve out its full term in office and continue the work of helping the Irish economy to recover.
Speaking in Ballina, the Taoiseach said he had made his views on the matter quite clear on a number of occasions.
He also dismissed criticism of the Government's record in office by the Fianna Fáil leader.
This morning Micheál Martin criticised pre-election promises already emerging from Government leaders.
Speaking on RTÉ's Morning Ireland, he said Mr Kenny is "deluded" and that in the last election he "got a massive mandate based on a series of promises, which turned out to be lies".
It came after comments from Mr Kenny and Minister for Finance Michael Noonan promising to lower income taxes in the run-up to and after the next General Election.
Asked about Mr Martin's comments, Mr Kenny said that they came from the leader of the party that wrecked the Irish economy.
He added that, as a minister, Mr Martin promised to abolish hospital waiting lists and had then responded "with a smirk" that he had no responsibility for that when he was subsequently questioned about it.
Mr Kenny also said the Coalition still had work to do and that it intended to fulfil its mandate completely, adding that the next election would take place early in 2016.
Also this morning, Minister Noonan said there will not be an election for another 15 months or so.
He said that things were going well in the economy and he ruled out an early election.
Also speaking this morning, Mr Martin responded to reports that the Government is likely to freeze the property tax until the end of 2018.
He said Fianna Fáil had already tabled an amendment last week that would have given effect to that.
He added that to date the Government has not taken on board any suggestions to scrap this review evaluation in 2016, which will lead to very significant increases in property tax.
"It is a runaway train. We do know that in urban centres in particular, the particular model adopted by the Government is very punitive and discriminates, particularly against those living in Dublin and in larger cities.
"In Dublin you are looking at potentially 50% increase in house evaluation over the period and that would have a very significant impact on the amount of property tax that people would have to pay into the future, and that is something that should have been closed off at its inception.
"It was pointed out to the Government at the time and they ignored everyone who pointed that out," he said.
