Boris Johnson’s plans to tear up post-Brexit arrangements for Northern Ireland have come under fierce attack from Washington, with senior congressmen on both sides of the US political divide warning the “irresponsible” move is a threat to peace in the province.

The Chairman of the US House of Representatives' Ways and Means Committee has issued a fresh warning that there will be no trade deal between the US and the UK if Brexit leads to the return of a hard border.
