Flanagan: I nearly broke for the border when talks faltered

The Stormont House Agreement, forged after 11 weeks of discussions, has resolved destabilising wrangles over the administration's budget and its non-implementation of welfare reforms while establishing new structures to deal with the legacy of unsolved Troubles killings.

It achieved less progress on other vexed disputes over the flying of flags and parading, but did set out new processes to examine how to find solutions to those matters in the future.

Minister Charlie Flanagan admitted this morning that it had been a long and challenging process.

“There was a time last week when Secretary of State Theresa Villiers was looking towards heading for the airport, and I was looking towards breaking for the border,” he said.

“But I want to acknowledge the contribution of everybody, in particular my Minister of State Sean Sherlock from the Labour Party, who played a really important role … the US administration … so I believe it was well worth it.”

The political deal will help build a peaceful future, US secretary of state John Kerry has said.

Mr Kerry said: "I commend the parties for working together through some very contentious issues - and finding solutions that will promote a more peaceful and hopeful future for the people of Northern Ireland."

US president Barack Obama and British Prime Minister David Cameron have also praised the deal.

Much of the plan has been facilitated with a £2bn financial package from the UK Government - an offer that combines some new money from the Treasury with enhanced borrowing access and flexibility.

Mr Kerry said: "This is statesmanship, pure and simple, and leadership by all parties to break a political impasse and avoid a fiscal crisis by resolving complex budgetary and welfare issues.

"The agreement reforms institutional arrangements, which will improve governance in Northern Ireland, and advances Northern Ireland's peace process by establishing new institutions to deal with the often-divisive legacy of the past."

He said those institutions included a historical investigations unit, an independent commission for information retrieval, an implementation and reconciliation group, and an oral history archive.

He said agreement on legacy issues was based largely on negotiations led last year by former special envoy for Northern Ireland Richard Haass, which broke up a year ago without success.

The deal overcomes nationalist concerns about welfare reform by enabling the Executive to establish and finance its own top-up fund to support those who will lose benefits when the policies are introduced.

The dispute, and accompanying multimillion-pound Treasury penalties for non-implementation, had threatened the future of the institutions.

While the Executive is still facing a hefty penalty to cover the period when reforms have not been in operation, the sum is much reduced on the £200m-plus bill it was facing.

The deal will enable ministers to balance the budget in the coming financial year.

Around £700m of the loan will fund a major public sector restructuring reform programme, which includes a voluntary redundancy scheme.

This proposal is part of efforts to rebalance an economy traditionally over-reliant on state jobs.

The Executive has also been granted the power to set its own rates of corporation tax in an effort to stimulate private sector growth.

This will enable it to better compete for foreign direct investment with the much lower rate of business tax in operation in the Republic.

The document sets out steps reducing the number of Executive departments and Assembly members.

New mechanisms, supported by £150m from the British government, will investigate historic Troubles killings, taking the place of police and the independent police ombudsman. Legacy inquests will remain with the coroners' courts.

The talks process culminated with a final 30-hour round of negotiations that saw politicians talk through the night at Stormont House.

The discussions were chaired by Ms Villiers. Minister Flanagan was also involved throughout.

Taoiseach Enda Kenny and Mr Cameron took part in an intensive session of talks in Belfast earlier this month.
