Minister for Communications, Energy & Natural Resources Pat Rabbitte has said that the Croke Park Agreement may have to be renegotiated in the future.

Minister Rabbitte said that the re-negotiation will depend on what happens in the eurozone, growth rates here at home and whether the agreement delivers reforms.

But the minister said that the Government will not unilaterally decide to freeze public workers' pay increments next year.

Speaking on RTÉ's The Week in Politics, he said that this would end the chances of getting "badly needed" reforms in the public service.

Minister Rabbitte said that when the agreement is "reviewed in due course" the Government would be free to sit down with the unions to re-negotiate it.

Public sector wages have been reduced by up to 15% since 2008 but the Government has been advised by senior officials at the European Central Bank and the Organisation for Economic Co-operation and Development to tackle pay again.

The Government stood by the Croke Park deal last week when unveiling the Budget finding €3.8bn savings through increasing taxes and cutting health, education and social welfare.
