Starmer is facing his judgment day over Mandelson missteps

Ahead of a showdown with MPs, prime minister looks like a man who is not really in control in his own government

Keir Starmer has spent much of the last 24 hours working on a plan for what senior government figures are already describing as his judgment day": his showdown with MPs on Monday over the latest Peter Mandelson revelations.

That the prime minister was apparently not told of Mandelson's vetting failure has provoked incredulity across Westminster and accusations he sacked a senior civil servant to save his premiership.
