The following is an edited version of the speech by Mr David Trimble to the UUP annual conference in Derry on Saturday:
When the police entered Parliament Buildings to search Sinn Féin's offices, it was not just another crisis in the peace process. It was the moment when the republican spin machine ran out of road.
Our scepticism about the oft-stated republican commitment to "conflict resolution" has proven to be well founded. Frankly, republicans' words are as devalued as Argentina's currency. Words like "the war is over", that might once have meant something, cut no ice today. Neither will deeds if, again, they are grudging and minimalist. We will not be satisfied with some phantom disbandment. The paramilitaries really do have to go away. Their day is over. This message goes out to loyalists as well. People are fed up to the back teeth with the racketeering and feuding that is disguised as loyalism.
I think this party has a lot to be proud of. Five years ago, faced with the challenge of confronting republicans politically, we did not flinch. Even after the DUP ran away, we did our duty and defended the unionist cause in the talks. And we did not just defend, we advanced.
All the constitutional issues - the consent principle; removal of articles 2 and 3; the Republic's improper constitutional claim; the end of the Anglo-Irish Agreement; ensuring that cross-Border arrangements were balanced and subject to a Stormont veto - on all these issues we succeeded. We also laid the basis for a return to Stormont. But we did not forget our determination to make sure that republicans reformed. Three times we gave republicans an opportunity, but opportunities are also challenges. Three times republicans failed. Three times we blew the whistle on their failure.
Now, we have to be fair, republicans have done some things too - not enough, but they have moved. They are not wholly unreconstructed, but this spring and summer the evidence of serious backsliding was overwhelming.
So, Mr Adams, it's up to you - only this time do not expect promises or beginnings to do the trick. It is time for conclusions, time for the transition that republicans say they are making to be completed. I have no intention of coming back to my party until it is demonstrably clear that this time obligations have been fulfilled.
Despite their anti-agreement rhetoric, the DUP have accepted it. They accepted it when they accepted their seats. They accepted it when they accepted office. They accept it when they accepted their part in an administration which included Sinn Féin.
That's the DUP for you: the party of the big lie and the half-truth. Increasingly, Peter Robinson is touting himself as the unionist Dublin has always been looking for. He is the darling of the nationalist press. Peter is trying to fulfil their agenda.
He pleads all too obviously for a specious renegotiation to spare his blushes while he courts Sinn Féin. Sleek mandarins in Dublin's Department of Foreign Affairs wonder: can Peter deliver? Let's be honest. Peter Robinson couldn't even deliver the milk! It is not the only mistake they make in Dublin. There is an ideological blind-spot there.
The doctrine of consent is widely accepted in Irish public life but its implications are not fully grasped. There is still an unwillingness to accept the depth and solidity of our community's commitment to the union and the political and cultural implications that flow from that. An example was this week's astonishing regurgitation by the Irish foreign minister of the 1980s phrase about a failed political entity. That rhetoric failed a long time ago.
How many Dáil members have had the courage of Ruairí Quinn to point out that the agreement will never be secure until the IRA disbands? Equally dangerously is the loose talk about joint authority. This is totally lacking in any shard of realism. Under the arrangement that we all agreed, Her majesty's government retains sovereignty - as they have just demonstrated by suspending the institutions yet again.
Furthermore, if we must all be punished for Sinn Féin's espionage and Stormont is in suspension, there can be no question of the North-South arrangements continuing to function as if nothing had happened.
Regardless of who starts it, the much recent violence has emanated from the fringes of our own community. I say to those loyalists who are seeking a political path and want to work for the development of their communities, please take up the challenge and make a positive contribution to the creation of lasting stability. But to those still addicted to violence, drugs and criminality, we say, in the name of God, go!
Part of the reason why people like the Assembly is the opportunity it gives for integrating nationalists fully into the political life of Northern Ireland. I believe it can be better done if at the same time we try to integrate everyone in Northern Ireland into the political life of the United Kingdom. We are still open to partnership government. We are committed to building better relationships. We continue, determined to achieve real peace.
The paramilitaries really do have to go away. This message goes out to loyalists as well. People are fed up to the back teeth with the racketeering and feuding that is disguised as loyalism
