He's not even a massive character, I don't think this is an ego thing, I don't think it's for the pension as we already established not in for the money. Boris Johnson was an ego thing, despite being totally out of his depth.
If you think the issue regarding the boats is such an easy fix, then I suggest you write to parliament and let them know. No, it's not his fault, it is a cheap shot as it's a long standing problem that all parties would inherit. The asylum seekers have been coming for years, first on the trains in Calais (remember all the camps along the train tracks?) then on boats. Under Starmer though, things have become tougher for asylum claims, people are being returned, numbers are down.
