Sinn Féin is calling on the Taoiseach to engage directly with the British Prime Minister in relation to the political impasse in the North.
"Now that the Scottish Independence referendum is over, I am calling on the Taoiseach to engage directly, as a matter of urgency, with British Prime Minister David Cameron in relation to the political impasse in the North which has resulted from the failure of unionist leaders to honour agreements reached," Sinn Féin leader Gerry Adams said in Dublin today.
“The refusal of Downing St to fulfil its obligations, which has contributed directly to the current difficulties, highlights the urgent need for the Taoiseach to hold the British Government to account.
“The Irish Government is co-guarantor of the Good Friday Agreement and subsequent agreements. The Taoiseach needs to be a champion for the Good Friday Agreement and the peace process."
Meanwhile the North's Deputy First Minister Martin McGuinness says the five parties in the Stormont Executive are agreed that the time has come for the British Parliment to give greater fiscal powers to the Northern Ireland administration.
It comes as Mr Cameron has promised to give greater powers to Scotland in the wake of the independence referendum.
Mr McGuinness says politicians in Stormont would like to set their own corporation tax and welfare rates.
"You know I was part of the negotiations, along with Peter Robinson and others, to argue with David Cameron that we should have power over our corporation tax, in terms of the ability to have it devolved, and also to set our own rate in conjunction with the rate in the south.
"Obviously I think this would be hugely appealind to foreign direct investors."
