Sunak is now wrapping up his speech.

He says that his hopes and plans for Northern Ireland "of course won't happen overnight."

He quotes one of the architects of the agreement, David Trimble, who said "there may be hills behind us, but there are mountains to climb."

He then recalls the murder of two lifelong friends at Poyntzpass in 1998 just weeks before the agreement was signed.

One was a Protestant, the other a Catholic.

He said their "remarkable friendship" encapsulates "the promise of the agreement".

"Together, we must and we can fulfil it," he concludes.

Sunak lists ways in which Northern Ireland has changed.

He mentions that a growing number of people in the electorate do not identify as nationalist or unionists.

He also is met with loud applause when he questions whether integrated education should be the norm, rather than the exception.

Sunak says in 25 years, we should look back on Northern Ireland being a more integrated and contented society.

But he mentions that the murder of journalist Lyra McKee and the shooting of Det Ch Insp John Caldwell - both by the New IRA - show how far Northern Ireland still has to go.

But, there is hope, he says, with a growing number of people in Northern Ireland are signalling that their patience for "thuggery" is over.

Sunak then turns his attention to economic growth.

He says the journey to prosperity "won't be easy - and we aren't there yet."

He says he will use "the full force of the government" to make Northern Ireland "the best place in the world to bring in investment, more jobs, and to attract people from around the world."

Sunak emphasises that "our focus must be on future."

"Getting Northern Ireland's institutions up and running again is only the beginning," he says.

"The future is enshrined in the text of the Good Friday Agreement.

"I will give everything to help deliver its vision."

Sunak says he will keep working to persuade all parts of the unionist community that a return to Stormont "is the best path".

"We will do that, we will talk, persuade and not give up," he continues.

He then speaks directly to the unionist representatives in the hall: "I urge you to work with us to get Stormont up and running again".

Sunak then speaks about the Windsor Framework, saying it strengthens Northern Ireland's place in the union.

He says he intends to build support for the deal across all communities.

But, he says, restoring the devolved intuitions at Stormont is the best path forward.

This point is met with a big round of applause.

Sunak now pays tribute to the contributions of the security services during the Troubles.

"I acknowledge at times they made mistakes, but I want to recognise their bravery, suffering and sacrifice. They created conditions to make their presence on the streets reduced, or entirely withdrawn," he continues.

With their "courage, imagination and perseverance", he says they possessed "the qualities that brought an imperfect but enduring peace to a place where no-one believed it would be possible".

He is now thanking those former and current members of the security services who are in the hall, as well as those no longer with us.

The prime minister says instead of glorifying violence, heroes should be made.

He continues by saying that making peace in Northern Ireland required imagination, and out of it three strands of equal importance came.

The principle of consent, in particular, is mentioned again, with Varadkar saying it allowed the people in both the Republic and Northern Ireland to support the deal by an overwhelming majority.

Sunak reflects on the how the peace deal came about - he says people on all sides showed "courage, imagination and perseverance".

He mentions some of its most important architects including John Hume and David Trimble - he says both were "rightly honoured" with their joint Nobel Peace Prize.

Mo Mowlam, Gerry Adams, the Women's Coalition and Bertie Ahern are also praised.

"These acts of courage were more powerful than a thousand bombs and bullets," he says.

He adds that there is nothing glamorous or glorious about violence or terror.

"They have never worked and they never will," he says.

The prime minister has taken to the stage.

He opens by paying tribute to the Good Friday Agreement, calling it the "extraordinary political achievement of our lifetimes."

"People on all sides did things once unthinkable in search for peace. A generation has grown up in a place more peaceful, more prosperous, and more at ease with itself - in circumstances more than perfect," he says.

The people of Northern Ireland need and deserve a functioning government, as well as the North-South Ministerial Council, Vardkar continues, comments which are met by applause.

He says the challenges facing people require Northern Ireland's leaders to make decisions.

He finishes his speech by quoting John Hume on unionists and nationalists working together.

Varadkar says it is on Northern Ireland's leaders to take the initiative and lead people into the future, and pledges that the Irish government, as co-guarantor of the agreement, will be there every step of the way.

Varadkar says the Irish government will continue to engage with all communities and traditions "to build a vision for our shared future, in an inclusive, constructive approach, underpinned by the agreement."

He says he hopes the Windsor Framework will play an "essential role" in securing additional investment in Northern Ireland.

He says the framework has been welcomed by the business community.

"A prosperous Northern Ireland is a place in which people want to live in, will want to make work," Varadkar adds.

"A place where young people will stay or return to."

Varadkar thanks countries which played a pivotal role in the peace agreement, including the United States, South Africa, Finland and Canada, as well as the European Union.

He continues: "Even hearing that list will evoke for each of us a roll-call of individuals to whom we owe deep appreciation."

He also extends his thanks to those who have "travelled the journey of peace with us", and "for your support over the decades".

He says that because of the peace and stability brought about by the agreement, now "parts of all of out futures are being built" in Northern Ireland.

"Companies from around the world have come to Northern Ireland, creating jobs and prosperity. Indigenous enterprise has flourished. I believe there is better to come," he adds.

Varadkar praises the principle of consent, which is included within the 1998 deal.

It allows people in Northern Ireland to hold British, Irish or dual citizenship and says Northern Ireland will only leave the United Kingdom if the majority of people there vote for that.

Varadkar mentioning the "growing middle ground" who hold more than one identity.

He reiterates the Irish government's agreement to work with the British government, as well as the Northern Ireland government, to make the process work across the islands.

He says Northern Ireland works best when the Irish and British governments work with an agreed strategy.

He mentions that he will meet Rishi Sunak later.

Varadkar says not many could imagine how much the Good Friday Agreement would transform relations between the UK and Ireland.

"As we face new challenges, we should not lose sight of this," he says.

He says the architects of the agreement understood the importance of looking to the future, quoting David Trimble: "We can leave it behind us if we wish.”

Varadkar says Trimble challenged everyone to make choices to avoid the mistakes of the past.

He praises the agreement for creating a space for people to articulate and work for the future they wished to see.

"It recognises that we don't need to have the same aspirations in order to co-operate and work together," he adds.

Varadkar pays tribute to the "architects who made a better future for all of us".

"I've had the privilege of living most of my life since the Good Friday Agreement was signed."

"I want to thank those architects from the bottom of my heart."

As Clinton leaves the stage to a standing ovation, the audience welcomes Taoiseach Leo Varadkar.

He begins his speech in Irish, and jokes Clinton and von der Leyen are hard acts to follow.

Varadkar describes the peace deal as challenging assumptions of what was once possible, and offered a pathway to a better future.

He recalls in the weeks and days leading up to its signing, many thought it wouldn't be possible to make the difficult compromises necessary.

He also praises the political leaders who pathed the way to reject divisions for a better future.

Wrapping up his speech, Clinton says it's time for "guys like me" to get out of town and let the people of Northern Ireland get on with the job.

He calls for more economic growth, less inequality and a better health service - but says issues like these can only be resolved with a functioning executive.

"I know it's what the people outside want," he emphasises.

Thanking the crowd for an unforgettable week, he asks the audience not to be discouraged as there are very few permanent victories, "all these old, ugly problems [are] always rearing their heads".

"You just have to suck it up and beat it back and deal with.

"You'll be fine if you remember what got you here...you are no longer walking on air against your better judgement," he adds with a nod to Irish poet Seamus Heaney.

Clinton goes on to say he's really worried about how far politics has drifted from "serious issues" that affect real lives.

He says some wish to focus on our differences, and a desire to convince us that "some of us are more human than others, some are more worthy than others, and our differences matter more than our common humanity."

"Our differences matter more than our humanity, but basic humanity will eventually reassert itself," he adds.
