I have read that it is rumoured that Tories are plotting to install Rishi Sunak as a caretaker PM.
I don't think installing Rishi Sunak as a caretaker PM will help much.
The problem is that the Conservative ideology doesn't work.
In fact, deregulation, selling off public assets to private commerce, prioritising profit over investing in infrastructure, lower tax for the richest, and letting markets decide things are the reason we're in the mess we're in.
