A poll published by the London-based Jewish Chronicle on Wednesday points to a sharp rise in the number of Jews in the United Kingdom who are seriously considering leaving the country if Labour leader Jeremy Corbyn becomes prime minister.
Some 40% of those questioned said they were seriously thinking about emigrating from the U.K. if Labour and Corbyn ascend to power.
Among those in the 35-54 age group, 50% expressed concern for their future, and 44% of the women polled echoed the sentiment.
Britain's former Chief Rabbi Lord Jonathan Sacks warned last weekend that most Jewish people in the country no longer know if the U.K. is a safe place to raise their children.
Sacks singled out Corbyn for failing to address anti-Semitic attitudes in the largest opposition party, saying the Labour leader would pose a danger as prime minister unless he expresses "clear remorse" for past statements.
Meanwhile, Jewish groups in the U.K. on Wednesday intensified their criticism of Corbyn and his supporters, after the Labour leader sought to impose a party line supporting the right to claim that Israel was established under racist circumstances.
Although Labour adopted the internationally accepted definition of anti-Semitism, it also backed a statement that adopting the definition "will not in any way undermine freedom of expression on Israel or the rights of Palestinians."
Gideon Falter, chairman of Campaign Against Antisemitism, said the statement was an "attempt to undermine the definition's validity, despite its adoption around the world and the fact that the definition is already heavily caveated."
Nevertheless, on Tuesday, a survey by British polling company Survation showed Labour extending their lead over Prime Minister Theresa May's Conservative Party to 4 percentage points, up from 2 percentage points. Most recent opinion polls show Labour ahead of, or level with the Conservatives.
