I am sure, when Biden came to power, his first act was a whole lot of “undo” actions against some of the most appalling bits of Trumpery. I think these were “executive orders”.
I really hope when Labour come to power in the UK they do something similar; a whole lot of Undos.
I’d also like to see lots of “finding out” activity in respect of lots of the criminal / conflict of interest activities of the tories or their mates too, ideally.
