I think that’s a bit harsh.
We know Mandelson was only picked because of Trump. There is no other explanation.
So to say there was no justification for his selection is wrong. The justification was the hope that they could keep Trump happy.
Without Trump in office none of this would have happened.
Starmer has had a crap hand of cards, but has played them badly to.
They probably thought Mandelson is one step removed from the young girls so is reasonable protected. No one knew about the latest stuff spying stuff. Hindsight is wonderful
