London and Dublin have a shared responsibility to ensure that the final steps are taken towards a "lasting and creative reconciliation" in Northern Ireland, the Irish president, Michael D Higgins, said in a historic speech to a joint session of parliament.
In the first address to the British parliament by an Irish president, Higgins hailed the 1998 Good Friday Agreement in Northern Ireland as a "momentous" achievement that was a key milestone on the "road to today's warm, deep and enduring Irish-British friendship".
Higgins added: "Our two countries can take immense pride in the progress of the cause of peace in Northern Ireland. But of course there is still a road to be travelled – the road of a lasting and creative reconciliation. Our two governments have a shared responsibility to encourage and support those who need to complete the journey of making peace permanent and constructive – enduring."
