There has been what has been described as a "major breakthrough" in negotiations on Croke Park II.

Labour Relations Commission Chief Executive Kieran Mulvey has been holding meetings with groups in a bid to secure a negotiated settlement in the row over proposals.

He has been meeting unions and management in the health and civil service sectors, as well as garda representatives.

The first breakthrough came with news that the Government had agreed to revise arrangements for pay cuts for employees earning between €65,000 and €100,000.

Instead of a three-year increment freeze, they will instead face two six-month delays in payment of increments.

In addition, pay cuts lost during 2013 and 2015 will be restored in two lump sums payable in 2017 and 2018. These concessions will not apply to those earning over €100,000.

The garda representative bodies left the LRC at around 8.30pm and it is understood that they will brief their respective executives tomorrow.

The GRA and the Association of Garda Sergeants and Inspectors were part of the 24/7 Frontline Alliance which led opposition to the Croke Park II proposals and refused to stay at the February negotiations to their conclusion.

Discussions with representatives of the civil service and health unions are expected to continue for some time.

Almost a month ago, public service unions rejected the Croke Park II proposals which involved pay cuts for those earning over €65,000 per annum, increment freezes of up to three years, longer working weeks for no extra pay, and reductions in premium payments.

The Government has repeatedly insisted that if a negotiated deal is not reached, it will legislate for pay cuts without consent.

Mr Mulvey is due to brief Minister for Public Expenditure and Reform Brendan Howlin tomorrow. Mr Howlin in turn will brief the Cabinet on Tuesday.
