Prime Minister Boris Johnson has started a series of meetings with political leaders on a visit to Northern Ireland.
As part of the New Decade, New Approach deal, the UK Government committed to working alongside the NI Executive to mark the centenary of Northern Ireland in 2021 - today's announcement is an important step towards realising this commitment, and delivering national recognition and global awareness of this important anniversary.
He will meet First Minister Arlene Foster and Deputy First Minister Michelle O'Neill.
Asked by Mr Lewis how he was sleeping, Mr Johnson replied it was "not an issue", adding that the baby "goes out like a light".
The centenary is an opportunity to celebrate the people, places and products of Northern Ireland, which has such rich sporting, cultural, entrepreneurial and academic talent.
Following formal acceptance of invitations to join the Centenary Forum and Historical Advisory Panel, it is expected that these groups will have their first meetings later this month.
Mr Johnson said the pandemic had demonstrated the strength of the United Kingdom and that Westminster and Stormont have worked closely together to get through the crisis.
"As the country begins to get back on its feet in the wake of coronavirus, we can not simply strive to rebuild, but we must commit to building back stronger than ever".
"I can not overstate how important the close co-operation that we have seen between central and devolved government will continue to be to this".
"Together, we will make sure Northern Ireland is ready to take full advantage of the many opportunities that lie ahead and that no part of Northern Ireland is left behind", said the British prime minister.
This will be his first visit to Northern Ireland since the COVID-19 pandemic, and Johnson wants to firm up ties badly strained by several years of acrimonious Brexit negotiations.
The Treasury has also protected more than 316,000 jobs and granted thousands of business loans.
It will be the prime minister's first trip to Northern Ireland since January, when a deal was struck to restore power-sharing.
"This is a fantastic opportunity for people right across the United Kingdom to celebrate Northern Ireland and its integral place within our union", he said.
Last week, Mr Martin suggested Britan may become less committed to Northern Ireland and said his Shared Ireland Unit in the Department of the Taoiseach was planning for this possibility.
