President-elect Joe Biden, an Irish American by background, has made his views known about the UK back-tracking on elements of the withdrawal agreement with the European Union and the possibility of border posts along the border between north and south.

Speaking to journalists in Delaware on Tuesday, Mr Biden said: “The idea of having a border north and south once again being closed is just not right, we’ve just got to keep the border open.”

He added that it had taken a great deal of effort to bring the Good Friday agreement into being – a deal brokered by the US. He said that the peace agreement should not become a casualty of Brexit.

Keeping the US administration happy is an important policy objective of the UK government as it hopes for a trade deal with the US post-Brexit.
