Michel says he feared the Good Friday Agreement would be "another paper in the museum of failed peace deals".

He pays tribute to the women of Northern Ireland who made the deal happen, and the "enormous contributions of visionary leaders" - naming Bertie Ahern, Sir Tony Blair and "so many others".

"Their efforts ensured the people's will didn't fall on barren ground," he adds.

He emphasises that the agreement must be protected and its principles adhered to.

Charles Michel continues by emphasising the duty to keep the spirit of the Good Friday Agreement alive.

Looking to the future, Michel pays tribute to the people of Northern Ireland and says the will of the people is the backbone for what the future of Northern Ireland can be.

"Today we must protect this agreement and stay true to its principles," he says.

Charles Michel is welcomed on stage with applause.

He begins by honouring the "strength and courage" 25 years ago that led to the peace agreement.

He describes it as a "remarkable and rare achievement" in light of the arc of human history.

Michel says against all odds, the deal was reached and gave a new beginning after years of armed conflict.

Clinton says it is her great pleasure to welcome EU Council President Charles Michel and EU Commission President Ursula von der Leyen, both of whom she describes as "strong advocates for democratic co-operation" under the Good Friday Agreement.

Clinton has come from the very first shared education campus in Northern Ireland, where Catholic and Protestant high schools share buildings for some subjects.

She says she was pleased to see the local high schools "working together, learning side by side, support, and sharing ideas."

She says she was stunned to see students in the midst of building an aeroplane.

"It's an example of the commitment and imagination we want to see across Northern Ireland," she adds.

Hillary Clinton walks onto the stage to a rapturous applause as she thanks everyone "for extraordinary days and events" this week.

She says it is an honour to be at the university alongside Taoiseach Leo Varadkar and Prime Minister Rishi Sunak.

Clinton begins: "We have had a chance to reflect on what has been achieved and really honour the citizens of Northern Ireland to make peace possible.

"We recognised those whose efforts often go unrecognised - women."

She says work to reimagine the future of Northern Ireland is front and centre today.

Here's a reminder of what happened yesterday during the celebrations of the 25th anniversary of the Good Friday Agreement.

• In what could be seen as a direct challenge to unionist politicians, Secretary of State Chris Heaton-Harris said a return to Stormont is the surest way to secure Northern Ireland's place in the union
• Irish Tánaiste Micheál Martin said that the Windsor Framework agreement between the UK and EU is the best deal available on post-Brexit trading for Northern Ireland
• There was a panel discussion between senior figures in each of Northern Ireland's five main political parties. DUP MLA Emma Little-Pengelly reiterated her party's commitment to stay out of power-sharing until further changes are made to Northern Ireland's position in terms of customs
• In a visit to Londonderry's Guildhall, former US president Bill Clinton paid tribute to John Hume and David Trimble as men "who put their lives and careers on the line" for peace

Here's a reminder of what took place on Monday, day one of the conference.

• Senator George Mitchell got things started with a speech reflecting on the Good Friday Agreement. In the afternoon a bust was unveiled to him at Queen's University, where he served as chancellor from 1999-2009

• In a panel discussion with some of the parties who negotiated the peace deal, former Sinn Féin leader Gerry Adams said it wasn't a "destination but rather the beginning of a new journey"
• A second party panel was also chaired by Nancy Soderberg in which former Alliance leader John Alderdice said that in the 1990s there was a "zeitgeist" in which leaders who resolved conflict were praised

• The final event of the day saw three former national leaders take to the stage in a panel chaired by Hillary Clinton. Sir Tony Blair, Bill Clinton and Bertie Ahern reflected on 1998 and how the Good Friday Agreement was delivered

In a matter of hours Rishi Sunak will bring this week’s mammoth series of events to a close.

He’s already referenced the anniversary during prime minister’s questions ahead of boarding a flight across the Irish Sea.

Security is becoming tighter as the campus prepares to welcome a VIP cast list with Sunak, Taoiseach Leo Varadkar and EU Commission President Ursula von der Leyen topping the bill.

The prime minister will then head to Hillsborough Castle for a special gala dinner.

It’s understood that before dinner is served he’ll hold meetings with the Stormont party leaders.

That's all from our live coverage from the Whitla Hall for now after another busy morning.

But it's not the end of our updates on Good Friday Agreement events, and we will also return to the Whitla Hall later.

The conference will conclude with speeches by leaders including Prime Minister Rishi Sunak and Taoiseach Leo Varadkar.

You can stream the keynote addresses at the top of this page.

Kennedy says Northern Ireland should be a place where children learn about history and not relive it.

He recites a section of a poem from a schoolboy from Donegal, who he met at the conference.

"Let's raise a pint of Guinness to the Irish and the Brits who put aside their differences for a future that uplifts," he reads from the poem.

Kennedy ends his speech saying he is excited and grateful to join the people of Northern Ireland on their journey and adds he "can't wait to see where we go".

Kennedy says he wants to ensure the benefits of prosperity and growth touch "every soul across this great place, from a vibrant city centre, past the falls and Shankill, the river Foyle, and through every corner of County Down."

He says that the people of Northern Ireland "aren't afraid of the hard stuff".

Joe Kennedy says two of his primary responsibilities will be getting businesses in Northern Ireland to expand their global footprint and attracting more businesses to invest here.

He says many executives are already aware of the case for Northern Ireland, including the talent and potential for market access that it has.

He adds that the sooner business leaders have clarity about the political future of Northern Ireland, the better it will be for the economy.

The US special envoy to Northern Ireland has thanked the organisers of the conference and the people of Northern Ireland for the welcome he and his family have received.

Kennedy recounts the places and visitor attractions he has visited in Northern Ireland including Derry's Walls, Carrick-a-Rede rope bridge, and a trip on a hyrdrofoil in Belfast Harbour.

He then reflects on the past 10 days he has spent in Northern Ireland.

"There are few places on this planet where the connection between the past and the present is so tangible," he says.

He adds that without peace there can be no prosperity.

Back in Limavady, both school principals say they are tremendously proud to have been honoured by Hillary Clinton.

“It’s a surreal moment,“ Rita Moore of St Mary’s says.

“Normally big events happen in Belfast or Derry.”

She says the schools are enriched by recognising all the things they have in common and by embracing their differences.

Darren Mornin from Limavady High School says Clinton’s visit is a source of pride for both schools.

He also stress that it is the ethos of shared education being recognised.

“We are every proud of our own identities and culture but we celebrate our difference” he adds

There were a few nerves before meeting Hillary Clinton, the head boys of both schools at the Shared Education Campus in Limavady admit.

“But it was fantastic to have Secretary Clinton here this morning, really excellent to hear what she had to say,”Jack McCorkell of Limavady High says.

Limavady is just a small town in Northern Ireland,Thomas Pattison from St Mary’s says, but the Clinton visit “just showcases the progress and how important the Good Friday Agreement has been”.

It is great to have someone like her come and recognise the importance of the shared campus, he says.
