Super Junior Minister Finian McGrath hit back at Alan Kelly, saying he should focus on the Labour leadership contest instead of his unpaid water bills.
Mr Kelly had criticised the Dublin North TD after he revealed he did not pay the charge.
The new Minister said focus should be on “hospital trolleys and people with disabilities instead of these issues” before Cabinet met this morning.
“It's not all about power, I'd like to say this to Deputy Kelly, it's about how you use power,” Mr McGrath said.
“Alan Kelly is obsessed, as we all know, with power. If I was him I'd focus on Brendan Howlin, Sean Sherlock or Jan O'Sullivan.”
“I haven't paid my water charges but accept the reality that if there are constitutional or legal challenges, I will look at that.”
Mr McGrath's Cabinet colleague and Health Minister Simon Harris believes he should pay water bills as “everyone should obey the law of the land.”
Mr Harris added that he'd let the Super Junior Minister “speak for himself” during the review of billing for water.
“I think it is important to pay your water bills. I think everyone should pay as it is the law of the land,” he said.
Public Expenditure Minister Paschal Donohoe agreed with Mr Harris, speaking outside Government Buildings.
“The principle is very clear, those bills that have been issued should be paid,” he said.
