There were 1,309 reported incidents of anti-Semitic crimes in 2016 – up 36 per cent on the previous year.
With as many as 60 per cent of victims staying silent about their ordeals, the true level of hate crime is even greater.
The scale of recorded anti-Semitic hate crime was revealed in a report by the Community Safety Trust.
David Delew, chief executive of the CST, commented: “Whilst Jewish life in this country remains overwhelmingly positive, this heightened level of anti-Semitism is deeply worrying and it appears to be getting worse.”
Amber Rudd has pledged try and eradicate anti-Semitic hate crime
Criminals who target Jews because of their faith were condemned by Home Secretary Amber Rudd.
“It is vital we ensure the safety and security of our Jewish community and this Government will continue to do all we can to stamp out these vile attacks and encourage those who experience them to come forward.”
Communities Secretary Sajid Javid added: “Anti-Semitism must be understood for what it is – an attack on the identity of people who live, contribute and are valued in our society.
British Jews are encouraged to report any hate crime they may have experienced
“Hatred and bigotry must not be allowed to grow without challenge. That’s why it’s so important that we all tackle the attitudes that fuel prejudice and speak out.
“We can never be complacent and must ensure that Britain remains a safe place for Jewish people.”
Labour Party deputy leader Tom Watson said: “The findings of this report are extremely distressing.
“I don’t want to live in a country where any member of the Jewish community feels unsafe, afraid or discriminated against and it is shocking that the number of anti-Semitic incidents is on the rise in the UK.”
The most common type of hate crime recorded by the CST was verbal abuse of visibly Jewish people in public.
One of several incidents highlighted by the CST involved six girls wearing Jewish school uniform on a bus in January.
Boris Johnson is under pressure to clarify whether dual-nationality Britons can travel to the US during Donald Trump’s travel ban.
The Foreign Secretary has insisted that Britons with dual citizenship would still be free to travel to the US – even if they were born in one of seven majority Muslim countries on Mr Trump’s blacklist.
Mr Johnson’s clarification followed urgent talks with the US President’s senior adviser and son-in-law Jared Kushner on Sunday to discuss the position of Britons, such as Olympian Sir Mo Farah.
However, advice on the US embassy in the UK website on Monday morning said there would be a 90-day travel ban to the US for those from the seven countries: Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.
And the notice said this included those with dual nationality.
It warned: “If you are a national, or dual national, of one of these countries (the seven majority Muslim countries), please do not schedule a visa appointment or pay any visa fees at this time.
“If you already have an appointment scheduled, please DO NOT ATTEND your appointment as we will not be able to proceed with your visa interview.”
The Prime Minister’s spokesman said he had not seen the statement on the website.
Former Labour leader Ed Miliband and Conservative MP Nadhim Zahawi, who was born in Iraq, have joined forces to call for an emergency debate in Parliament on the travel ban.
It comes as more than one million people signed an online petitioncalling for Mr Trump’s upcoming state visit to the UK to be blocked.
But Downing Street has insisted Mr Trump’s state visit will go ahead.
Her spokesman said Mrs May was “very happy” to extend the invitation to Mr Trump and added “we look forward to hosting the President later this year”.
Protests over the travel ban have also been planned in the UK for Monday evening. They are scheduled for 6pm in London, Manchester, Bristol, Brighton, Liverpool, Glasgow, Edinburgh, Cardiff and Swansea.
Labour leader Jeremy Corbyn said the ban was “outrageous, illegal and immoral” and that “we should stand up for the values that we believe in”.
He said he would be at the protests if he can but would definitely be sending a member of his team to the London protest.
Welsh First Minister Carwyn Jones has spelled out his opposition to a state visit by Mr Trump with the Prime Minister during talks in Cardiff.
A spokesman for the Welsh Government said: “The First Minister raised serious concerns about how the recent US immigration order was handled by the UK Government, and his belief that a state visit would be difficult in the current circumstance.”
Thousands of children are being taught in unregistered schools across England, many more than previously thought, Ofsted’s chief inspector has said.
Sir Michael Wilshaw said a crackdown had found more than 100 suspected illegal schools – half of which were faith-based, Ofsted said.
Roughly a third of them were Islamic and a sixth either Christian or Jewish.
Seven warning notices have been issued to schools in London, Wolverhampton, Birmingham, Luton and Staffordshire.
Any school offering 20 hours of lessons a week must be registered.
Unregistered schools are those that operate outside the supervision of the Department for Education, local authorities or Ofsted inspections.
They are often run by faith groups and there are concerns about the safety of pupils in their charge.
In a letter to Education Secretary Nicky Morgan, Sir Michael said his team of seven experienced inspectors, working closely with DfE officials, had identified more than 100 suspected unregistered schools across the country since January.
“The evidence they have gathered so far during this short period firmly reinforces my belief that there are many more children hidden away from the view of the authorities in unregistered schools across the country than previously thought,” he said.
In the past month alone, seven unregistered schools with more than 400 children had been identified, Sir Michael told BBC Radio 4’s PM programme.
He said his inspectors found schools operating in warehouses and old factory buildings, and the establishments were “often charging parents for the privilege”.
He said the children were in “very serious danger” and not just from the “filthy” premises, with open drains running through some of them.
“If the people in these institutions are not carefully vetted and they are not, then the wrong sort of people could be looking after these children,” he said.
“And they could be associating with people who have extremist views.”
Sir Michael added: “These children are not being educated well, the curriculum is being narrowed, often only religion being taught, homophobic literature being found.”
These schools were using the freedom of parents to home educate their children as a cover for their activities, he said.
“I think the rules around home education need to be tightened,” he said.
“There is a correlation between the growth of home education and the number of illegal schools that are now operating.”
He called on local authorities, who he emphasised “are charged with the responsibility of safeguarding all children whether they go to a local authority school or academy or free school”, to show vigilance and share intelligence.
Many of these schools are charging parents thousands of pounds, Sir Michael said.
Talking about the religious schools in particular, he said parents were sending their children because they were not satisfied with mainstream education “because music, for example, could be taught or creative subjects which they disapprove of”.
“And some religious leaders are encouraging their parents to do this – some leaders in the Muslim community and the Jewish community are doing it”.
A Department for Education spokesman said nothing was more important than keeping children safe, adding that councils have clear powers to take action where there are concerns.
“We have given new resources to Ofsted to investigate unregistered schools and to prepare case files for prosecution by the CPS.
“We have consulted on new measures to protect children in out of school settings offering intensive education. We received a large number of responses, which we are now considering, and will make a further announcement in due course.”
Shadow education secretary Lucy Powell accused the government of being “asleep at the wheel” and allowing extremely worrying and potentially dangerous practices to evolve in the schools system.
“The Tories’ education policy has led to a fragmented schools system lacking robust local oversight to spot and tackle serious problems early on.
“As a result, many children are dropping off the radar or ending up in illegal, unregistered schools for months or years, where they are at risk of being exposed to harm, exploitation, or the influence of extremist ideologies.”
A spokesman for children’s charity NSPCC said: “When picking these institutions, some parents might not know that such ‘schools’ are unregistered and employees haven’t had the proper background checks or safeguarding training and are unaware of the risks these pose to their children.
“It’s vital that every individual who works with children passes these checks to help keep every child safe.”
