Sinn Féin president Mr Gerry Adams has urged the British government to abandon attempts to woo Democratic Unionists and press ahead with troop cuts in Northern Ireland.
Mr Adams insisted Dublin and London had spent long enough working on the DUP and should begin moves on a military scale-down.

Still angered by the failure to restore power sharing during the Leeds Castle summit in Kent, when it seemed unprecedented IRA disarmament was on the table, he claimed unionists should not be allowed to grasp for other excuses to avoid a settlement.
"Every time there appears to be movement on one issue, for example the whole big issue was around the IRA, every time there appears to be some ability to resolve these issues then they (DUP) move on to some other issue," Mr Adams said.
"They're obviously playing for time and our position is that they should not be allowed to do that. This phase of pandering to DUP intransigence needs to end."
The DUP, which has pledged to transform the Belfast Agreement, wants Cabinet Ministers to be more accountable to the 108 members of the Stormont Assembly.
Both Sinn Fein and the SDLP have fiercely resisted the move. Mr Adams insisted any momentum from the three-day talks in Kent has not been followed up and called for the two governments to move on.
Despite accepting that as the biggest unionist party in Northern Ireland the DUP could refuse to sit in any coalition cabinet, the Sinn Fein leader demanded action on other outstanding parts of the peace package.
"In terms of political institutions the DUP can refuse to participate and by their absence make that part of the Agreement very difficult," the West Belfast MP accepted. "But the DUP really have no say on issues which are the responsibility of the governments.
"On all these issues, whether it's equality and human rights, whether it's demilitarisation or whether it's justice then the governments should move ahead and they should make it clear to the DUP that the Good Friday Agreement is going to prevail."
Challenged over whether this would include signing off on IRA decommissioning as well, Mr Adams stressed that all armed groups would have to be part of the agreement.
"The reality is you need an overall political agreement in an overall process of sustainable change," he said. "As far as I'm concerned all of these issues need to be tackled."
