DONALD Trump has mistaken Ireland for being part of the UK after a discussion with the prime minister of Ireland, Leo Varadkar. 

The US president was speaking with Varadkar about the coronavirus measures in place in Ireland. 

Responding to Varadkar, Trump said: "And one of the reasons the UK has basically been ... it's got the border, it's got very strong borders, and they're doing a very good job, they don't have very much infection at this point and hopefully, they'll keep it this way."

This mistake comes at a crucial time for the UK/US relations, where trade deals with America are being considered for the post-Brexit UK. The Republic of Ireland, an independent nation, is not leaving the EU and is not part of the UK.
