US Speaker Nancy Pelosi warns against weakening peace deal

US Speaker of the House Nancy Pelosi has begun an official visit to the Republic of Ireland. Speaking on the eve of her visit, she said there would be 'no chance whatsoever' of a post-Brexit trade deal between the US and UK if there were any weakening of the Good Friday Agreement. Ms Pelosi is expected to meet Taoiseach (Irish Prime Minister) Leo Varadkar on Tuesday evening. It is understood Brexit will be one of the main topics of discussion. She will be accompanied by a delegation of Democrat and Republican congressmen and women. The delegation is expected to visit Northern Ireland later this week.
