This Jewish Chronicle article https://www.thejc.com/news/uk-news/labour-supporters-in-bristol-erect-banner-with-1.439599 reports that:
'A giant left-wing political banner in one of Britain's biggest cities has been condemned as antisemitic for portraying Theresa May wearing Star of David earrings.
The banner, which was hung at the Bearpit roundabout in Bristol, depicted Jeremy Corbyn and Theresa May facing each other, with positive slogans endorsing Jeremy Corbyn and negative statements about Theresa May's policies.
As well as the earrings, the word "Balfour" was also written on the poster next to Theresa May. This November will mark the centenary of the signing of the Balfour Declaration, which called for "the establishment in Palestine of a national home for the Jewish people", as well as saying that "nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country".'
People seem puzzled the other week when it was reported that Jews were deserting the Labour Party, I believe that the figure quoted was just 13% of British Jews would vote Labour. The Labour Party, consciously or otherwise, have made the decision that there's more Muslim votes than Jewish votes and that they side with Muslims over more elements of foreign policy anyway.
Anti Semitic sentiment long just below the surface on the left of British politics has been given a degree of legitimisation and that genie will not now be able to be returned to its bottle.
If the worst happens and a Jeremy Corbyn lead Labour Party becomes the head of a UK government then I strongly recommend that all British Jews leave the UK before it is too late.
