SINN FEIN finance spokesperson Pearse Doherty has laid into Fianna Fail and Fine Gael for trying to 'hoodwink people' into believing they will deliver change.
Doherty said that both Varadkar and Martin's parties were "not short on spin, but are light when it comes to delivery".
He claims that FF and FG's interests are to maintain power and to keep Sinn Fein out, not to serve the wishes of the Irish public.
The criticism comes after the news that the two civil war parties have agreed the framework for a new coalition government.
Speaking about the formation document, Doherty said: "Today's paper is nothing more than a wish list of vague promises - the aim of which is to keep Sinn Fein out of government and hoodwink people into thinking they will deliver the type of change that people voted for in the general election.
"The reality is that most of what is in this document will never see the light of day.
"Everyone knows they can't be trusted, and that a government involving both Fianna Fail and Fine Gael will not deliver for ordinary workers and families," he added.
"Delivering the change that people voted for means delivering the biggest house building programme in the history of the State, it means being able to see a doctor when you are sick, it means delivering truly affordable childcare, it means setting out proper climate change targets and it means ensuring that workers can avail of a State pension at 65.
"Real change requires a stable government that will lead - and deliver - and that is what Sinn Fein want to see," he concluded.
Following February's general election, no one party managed to secure a majority, though Sinn Fein won the popular vote.
With coalition talks stagnating, it appeared as though the country would head for a second general election, where Sinn Fein were expected to field significantly more candidates, and likely win more seats - though the covid-19 crisis put paid to that idea.
