And I agreed that I couldn't find a source. Did you not see that bit?
The fact that Starmer is actively supporting and funding isreel's genocide of Palestinians, and he has isreeli family and close ties to the country, should really not be ignored though.
If our next PM has a spouse with russian heritage and half the family lives in russia, and this PM starts massively funding and politically supporting the russian invasion of Ukraine, while imprisoning pro-Ukraine reporters and protestors... would you also claim the PM having russian family and close ties to russia, was completely irrelevant to their motives?
