Within months of the Good Friday Agreement, two significant days - in May and August 1998 - put the peace process to the test but ultimately demonstrated how far the people of Northern Ireland had come.

In this episode, Bertie speaks to those who campaigned in the referendum that was held on 22nd May 1998, including Tony Blair, Dawn Purvis, and Monica McWilliams while Martin Mansergh explains the delicate planning behind the constitutional changes that were put to the people on the same day in the Republic.

Just a few months later, the hard-fought-for peace was jeopardised when the biggest single atrocity in the history of the Troubles occurred in Omagh. Tony Blair, Liz O’Donnell, David Andrews, and Sean Farren share the shock they felt on that horrendous day and how the cruel bombing only served to increase their determination to move forwards.
