The World Tonight

US President Donald Trump has threatened the BBC with a $1bn lawsuit over edits the Panorama programme made to a speech he gave before the January 6 Capitol riots. We assess the significance of the lawsuit and the resignations of the Director General and the CEO of BBC News. Also on the programme: why Democrats aren’t happy about a deal aimed at ending the longest government shutdown in US history; and on a rare trip back home, a UK-based Russian writer finds out how people are dealing with the war in Ukraine.
