Starmer has had nerves of steel this week and kept his cool.
Nothing he says, (or Sunak for that matter) about the conflict in Gaza will change a thing in that terrible situation. However, what has he signalled about his leadership is that he's not going down the road of playing 'international socialist' like so many who have led the Labour party in recent times and that has kept them out of power and the Tory's in power, for over a decade.
Yes, it may come back to bite him in a GE, in that he may still win an overall majority, but will he have a large enough majority to really bring some Labour ideas to fruition in Government and to move the dial positively in favour of the majority of people who keep the wheels turning in the UK.
