Whatever the outcome of the Westminster election, the Belfast Agreement must not be renegotiated, the leader of the Alliance Party has said.
Speaking at the launch of his party's manifesto, Mr Sean Neeson said political parties in the North had "failed to preserve the spirit of spring 1998", when the agreement was reached.
"Tribalism is destroying the agreement," Mr Neeson said, but warned that in whatever negotiations came after the election it was important for both governments to demonstrate that it "is not up for grabs, is not up for renegotiation".
"What we want to see happening is the Good Friday agreement being implemented in full. The recent polls have clearly shown that people in Northern Ireland, whether unionist or nationalist, want to see the agreement succeed."
Mr Neeson said his party supported the new Police Service of Northern Ireland and said the refusal of the SDLP to say it would do the same was creating enmity between the unionist and nationalist communities.
"That sort of politics, I believe, is misleading the electorate and their electorate in particular. We all know they are going to join the Police Board, so why not do it now?"
Alliance has stood down in a number of constituencies and Mr Neeson berated the SDLP and Ulster Unionists for not showing "the same statesmanship and leadership that we have shown to ensure the maximum number of strongly pro-agreement candidates are elected".
He said politics in the North now needed to be about "more than just the agreement", and needed to produce ways of creating a shared non-sectarian Northern Ireland. To help achieve this his party was calling for the introduction of anti-hate laws which would cover sectarianism.
Other measures called for in the manifesto included the introduction of weighted majority voting in the Assembly. Mr Neeson said the current system, where votes were counted in terms of unionist and nationalist, amounted to a "tribal head count".
The party is also calling for the reform of the Barnett formula, used to calculate Northern Ireland's share of funds from the British treasury.
"In addition we believe the Assembly must have tax-varying powers. With this ability we can promote economic growth and raise the necessary funds to provide a better quality of life," Mr Neeson said.
In education, the party promised to work for the abolition of the 11-plus exam and of university tuition fees. It is also to press for the provision of more places in integrated schools.
