You appear to make the assumption that the majority of Jews are Zionist.
I am betting not many of them speak Urdu.
I would imagine that substantially all people of Jewish descent in the UK would be Zionists to the extent that they support the existence of the state of Israel. The extreme Zionism in some parts of the Israeli political spectrum that extends that to land that is currently Palestine is probably less widely shared. But the leaflets somehow conflated Starmer as head of state meeting people such as Narendra Modi and Netenyahu with being islamophobic.
Polanski this morning was forced to acknowledge that of course as head of state it was appropriate to meet with these people (which presumably would entail being in the same place and photographed), but not to be "chummy" with them.
It's not even student union level politics, it's more like high school.
