There was an analysis of Johnsons downfall a while back. Some people noticed it was predicated on questions Starmer had put to Johnson in the cut and thrust of a debate months before.
Something for the "Starmer is useless" camp to ponder.

A day after ITV News published a leaked video of a mock press conference appearing to confirm reports of a party, Sir Keir grilled Mr Johnson in the Commons again.
The public "were lied to", he told Mr Johnson, to which he replied: "I have been repeatedly assured since these allegations emerged that there was no party, and that no Covid rules had been broken. That is what I've been repeatedly assured."
These two statements from December 1 and December 8 amounted to one complete denial and another insistence that, whatever happened, he was unaware of any rule-breaking.
It was these questions from Sir Keir that became central to the 14-month investigation by the privileges committee, which ruled Mr Johnson recklessly misled MPs.
