In this bonus episode, Paul and Nathan react to Boris Johnson's bombshell departure from the House of Commons before an explosive report from the Privileges Committee ruled he deliberately misled MPs throughout the partygate scandal.

They examine the former prime minister's claims of a "witchhunt" against him and return to their sources to debunk his allegations his downfall has been orchestrated by anti-Brexit plotters.

So why did the cross-party MPs decide against Mr Johnson? Does his departure offer any closure for those who suffered most during the pandemic? And is this the final chapter in the partygate scandal and in Johnson's political career?

This bonus episode of Partygate: The Inside Story was written by Paul Brand, Nathan Lee and David Williams. It was produced, edited and directed by David Williams. The executive producer was Matt Williams.
