The Tanaiste has been accused of having “no empathy” for those caught in the renting and housing crisis.
Eoin O Broin said Leo Varadkar is “directly responsible” for their hardship, more than any other politician.
The Sinn Fein housing spokesman also accused Mr Varadkar of failing to understand the housing crisis.
Mr O Broin’s criticism of the Tanaiste was in response to the budget, which he claimed failed to include any measures to address the housing crisis and “sky-high rents”.
“The last time I raised the plight of private renters with the Tanaiste was in September. I reminded him that during his decade in power, rents have increased 100%,” Mr O Broin told the Dail.
“When he was taoiseach, the number of properties in the rental market dropped by 20,000. Instead of dealing with the issue, the Tanaiste went on the attack.
“He avoided, misdirected and misrepresented.
“He may think that this kind of belligerent approach is good for his satisfaction ratings but it actually confirms that the Tanaiste has no empathy.
He, more than any other politician in the Government, is directly responsible for that hardshipEoin O Broin, Sinn Fein
“He lacks that basic human ability to put himself in the shoes of other people enduring hardship. Why would he?
“He, more than any other politician in the Government, is directly responsible for that hardship, with working single people and couples desperately trying to save for a deposit.
“Separated and divorced people who have lost their family homes, families recovering from Celtic tiger-era home repossession, students forced to choose between sky-high rents and crippling commutes, and modest-income workers approaching retirement and looking nervously to the future.”
Mr Varadkar said the Dublin Mid-West TD’s comments are a “classic Sinn Fein tactic”, adding that it was “beneath him” to personally attack him.
It will not just benefit renters but all workers and indeed people who are on welfareTanaiste Leo Varadkar
Mr Varadkar went on to say that the housing crisis affects different people in different ways.
“Some people are struggling to pay rent, other people are struggling to pay mortgages, and there are people in their 30s and 40s still living at home with their parents because they are struggling to raise a deposit to buy a house, since that is what they want to do,” Mr Varadkar added.
“In the budget, we introduced income tax and welfare packages that will benefit people across society.
“It will not just benefit renters but all workers and indeed people who are on welfare. We stand over the approach that we took in this budget.”
Mr Varadkar pointed to the Government’s decision to extend the Help to Buy scheme, claiming they are making record levels of investment in social housing, cost rental and affordable housing.
“Renters who want to become homeowners are much better off under this Government than they would be under Sinn Fein,” Mr Varadkar said.
“It would give 1,000 euro as a rent credit with one hand and take away 20,000 euro to 30,000 euro with the other hand by abolishing the Help to Buy scheme.
“There is no doubt that renters who want to buy would be better off under this Government than they would be under Sinn Fein.”
