Almost four in ten British Jews say they hide their faith for fear of anti-Semitic attacks, and one in three have thought about leaving the country because they don’t feel safe anymore, a poll conducted by YouGov found.

Campaign Against Anti-Semitism chairman Gideon Falter told Sky News the findings should be "a shot across the bows" for the authorities.

"We've got a very serious situation where on the one hand, British society is very effectively starting to shun anti-Semitism, but the institutions we rely on to protect our communities are not doing enough,” he said.

"We've been talking about it for years and years. When are they going to wake up?"

The YouGov survey, carried out by the CAA, also found that anti-Semitic attitudes in UK society were declining – down from 45 percent in 2015 to 36 percent in 2017.

Some 65 percent of the nearly 4,000 respondents said they believed the government wasn’t doing enough to protect them – just last month police figures showed a 45 percent increase in hate crimes against Jewish people – and the survey found that only 59 percent of Britain’s 270,000 Jewish people feel welcomed in the UK.
