Nigel Farage is a guest of Donald Trump as he's sworn in as US President for the second time today. Does it matter that the Prime Minister, like most other European leaders, wasn't invited?

We discuss with Bloomberg's UK political editor Alex Wickham. Hosted by Stephen Carroll and Caroline Hepker.
