I wonder.
While working for Boris he was protected and publicly supported by the PM and the Cabinet, even when he made a complete ass of himself over his multiple excuses for breaking isolation rules.
Having resigned, he has turned ferociously on his former collegues publicly, the opposite of the way they treated him.
So, however good he might be, there is now a glaring mark on his CV that shouts loud and clear, NOT TO BE TRUSTED.
In any future post his collegues are going to want to give him a very wide berth.
It sounds as if his leadership skills were poor to start with, and NOTHING that he has done recently has shown that he has improved.
Perhaps his best chance of a job might be to go and work for Donald.
At least they seem to have a lot in common.
