In retrospect being loyal , all in supporters of Labor was not so good for the Jews.
British Jews have not historically been members of the Labour Party.
They don’t particularly vote in a block like the USA, but leaned more to the Torie (Conservative) side, at least compared to the general UK population.
That said, the last 3-4 years have been all over the place, but generally more “right” than the UK population as a whole, but also a large abandonment of both the Tories and Labour, with 40% splitting off to go to various other parties (mainly Reform (very conservative), Green (basically commies), or other, even smaller, parties).
Of course, their “right” is probably left of center in the USA.
