Joe Biden warns UK not to damage Northern Ireland peace over Brexit – video

Joe Biden has underlined the importance of ensuring peace in Northern Ireland is not jeopardised by post-Brexit tensions. Asked about a UK-US trade deal, the US president told reporters in Washington on Tuesday: 'There are two separate issues: on the deal with the UK, that continues to be discussed, but on the protocols, I feel very strongly about those. It was a major bipartisan effort made, and I would not at all like to see - nor, I might add, would many of my Republican colleagues - like to see a change in the Irish accords, and the end result having a closed border again'
