The Irish Government is to push European leaders to slash the cost of its crippling bank bailout after it secured resounding support for the fiscal treaty.
Taoiseach Enda Kenny said he raised the issue of the multibillion rescue in several phone calls with EU chiefs, including Germany's Angela Merkel, once the referendum result was confirmed.
After securing a confident 60% majority in the popular vote Mr Kenny said the bailout for bust banks - more than 46 billion euro (£37 billion) - must now be included in wider efforts to kick start the European economy.
"Ireland's banking debt must form part of that solution," he said. "One of his junior ministers, Brian Hayes, insisted the focus was on the 34 billion euro plus (£27 billion) burden left behind by rogue lender Anglo-Irish Bank.
Five of Ireland's 43 constituencies rejected the treaty plan for tighter budgetary control from Brussels including both electoral regions of Donegal and three others in Dublin, one of which is home to two senior government figures, Communications Minister Pat Rabbitte and Mr Hayes.
Sinn Fein claimed some credit for forcing a strong No vote but failed to secure a success in party president Gerry Adams' backyard of Co Louth.
And the splits in support around the country were widely seen as highlighting a growing class divide with many of the more affluent areas showing strong backing for the treaty while traditionally working class areas of Dublin and Cork came out against the pact.
Tanaiste Eamon Gilmore, Ireland's deputy prime minister and Labour leader who has seen support for the party diminish in opinion polls this year, also backed the Taoiseach's call for a debt deal.
"This was not just an exercise - asking people to vote Yes - it was also an occasion where we listened to what people where saying," he said. "We do need to have a deal in relation to our bank debt. We do need to see progress upon it."
The first opportunity for the treaty success and the potential for a growth pact to be discussed will be later this month at an informal European summit.
