The Chairman of the Fine Gael party has today called for elements of the Croke Park Agreement to be renegotiated.
Deputy Charlie Flanagan said all sides should sit down together to discuss the payment of increments, which are not part of core pay.
However, his comments put him at odds with Tánaiste Eamon Gilmore who said earlier that the deal would be honoured until its conclusion in 2014.
Employers group IBEC have also called today for the deal to be re-opened.
Speaking at the Fine Gael think in in Co Mayo, Deputy Flanagan said that some aspects of the Croke Park Agreement, such as increments paid to public servants, need to be re-examined.
"I don't believe a unilateral re-negotiation of the Croke Park Agreement is possible or feasible, " he said.
"If there are aspects of the agreement that require all parties to resume round-table talks well then, that may, in the circumstances, be necessary."
