Biden's Northern Ireland visit prompts calls for Stormont return and disrupts alleged bomb plot.

UK Chancellor Rishi Sunak has called on Stormont politicians to "get on with the business of governance" ahead of US President Joe Biden's visit to Northern Ireland on Tuesday to mark the 25th anniversary of the Good Friday Agreement. Sunak praised the "bravery, perseverance and political imagination" shown by the leaders who shaped the peace deal, which ended Northern Ireland's decades-long violent conflict known as the Troubles. However, the DUP is boycotting Stormont because of objection to post-Brexit trade rules agreed between the EU and UK.
