UK officially leaves the EU

Britain has officially left the European Union - prompting celebrations and protests - and kicking off a further tense period of negotiations on their future relationship.

Also on the programme: US Democrats have accused Republicans who voted not to call witnesses at Donald Trump's impeachment trial of conspiring in a cover-up. And: The United States has announced that foreign citizens who've been in China in the past fourteen days will be barred from entering the US, to control the spread of the coronavirus.
