I rise to speak as the vice-chair of the British-Irish Parliamentary Assembly and the all-party parliamentary group on Ireland and the Irish in Britain. Despite the border being one of the principal issues in the phase 1 agreement, there has been very little debate or understanding in this House about the context of the border issue with Ireland, and that is a huge problem. Phase 1 is hugely welcome. Our Prime Minister has signed up to it on behalf of the United Kingdom, and there is to be no ambiguity or rowing back from it. On day five of these debates, the hon. Member for North Down (Lady Hermon) said that she remembered exactly where she was when the Good Friday-Belfast agreement was announced. That is true for many of us. I am one of the millions of British children of Irish immigrants who grew up in the 1970s and 1980s. It was difficult. The violence and murder on the streets of Northern Ireland and Britain hung over our communities and fuelled anti-Irish sentiment here. That changed in the 1990s. The Good Friday agreement is an exemplar across the world of dealing with long-standing conflict. The UK and Ireland are its guarantors, and our joint membership of the EU, our shared regulations and our customs union are the foundation on which it is based. The Good Friday-Belfast agreement was not just about Northern Ireland and it was not just about politics. It was about the relationship between all the people on these islands. We have more in common: until 100 years ago, we were one country. My grandparents were born in Mayo and Cavan under the auspices of this Parliament, just like me when I was born in London. Our legal and political systems are akin, which is why the Republic of Ireland is our greatest ally in the EU. For years, hundreds of weekly meetings have taken place between our officials and our politicians as part of the EU. These will cease, and the Good Friday agreement now needs to come into its own and deepen the north-south and east-west strands. The debate about the border is not about wandering cows and cameras. The absence of a border is about recognising our commonality and our mutual interest. On the British-Irish Parliamentary Assembly, we are concerned that there is no longer the necessary knowledge and experience in this Chamber of the British-Irish relationship, and we have been considering how to support hon. Members to develop that understanding and to undertake greater cross-party and jurisdictional work. I hope that the House of Lords will have more debates on this issue than we have done. In my early days as a Member, Mr Speaker, we had the privilege of hearing the noble Lord Bew speak in your rooms about Charles Stewart Parnell and the great arguments that raged in this place throughout the 19th century. We could perhaps arrange for more speakers from all communities, and we could encourage the Select Committees and the all-party parliamentary groups to share understanding across these islands and to develop those deep relationships. Most importantly, we need to build on what we have and not go back. Voices on both sides of the House are crucial to that.
