As with most political scandals, the heat in the Angela Rayner housing row is less about the (alleged) crime and more about the (alleged) cover-up.

Starmer: Rayner tax story is ‘smear’
For a politician known for her straightforward and unvarnished manner – who has often been on the front foot chastising Conservatives for all manner of indiscretions – a humbling like that may prove too severe to survive.
