The number of hate crimes against Jews in Britain has reached a shocking new high, campaigners warn today.

An alarming new report shows that police forces recorded almost 1,000 anti-Semitic offences in 2015 – a 25 per cent rise on the previous year.

Violent attacks on Jews soared by 50 per cent and yet there was a worrying decline in the number of cases where suspects were charged.

Campaigners fear the worrying trend is being driven by Islamists, neo-Nazis and far-Left activists and students, who use social media to share sickening images similar to those seen in Nazi Germany.

In one shocking case, a mob shouting ‘Kill the Jews’ stormed a synagogue in Stamford Hill, North London, smashing windows and attacking worshippers.

The report says that there has been a ‘growth in anti-Semitism as a core part of far-Left’ ideology. The findings come as the Labour Party is gripped by anti-Semitism allegations: MP Naz Shah and former London Mayor Ken Livingstone have both been suspended in the past week, and an internal investigation has been set up by beleaguered party leader Jeremy Corbyn.

Last night, Gideon Falter, chairman of the Campaign Against Anti-Semitism, which published the report, said: ‘This data should alarm those responsible for enforcing the law. They are failing British Jews badly.

‘If the situation continues to deteriorate, the Jewish community will be faced with the kind of rampant anti-Semitism seen in other European countries, which has left Jews feeling fearful and abandoned, and many of them convinced that they have no choice but to emigrate.’

He added: ‘Britain’s fight against anti-Semitism and extremism cannot be allowed to fail.’

The charity asked every force in Britain how many anti-Semitic incidents and crimes they had recorded in each month of 2014 and 2015, as well as the number that involved violence, and the proportion that led to prosecutions.
