Downing Street urged the public to stand up to hate crime in January after the UK’s equalities chief warned a surge in violence could be sparked by triggering Article 50.
The Prime Minister’s official spokeswoman said people should “call out” any attacks on EU citizens in the UK that might follow the start of Brexit’s formal process.
“Where there is hate crime, we should stand up to it, call it out and take action and make very clear it is not acceptable in this country”, she said.
Hate crimes surged in the month following the UK’s vote to leave the EU last June, with a 41% increase in reports to the police, compared to the previous year.
There were 3,886 such crimes logged in July 2015, rising to 5,468 in July 2016, according to the Home Office.
The number of hate crimes overall in the year 2015-16 was up 19% on the previous year.
Last year's figures show that 62,518 offences were recorded by police.
Of these, 79% were motivated by race hate, 12% by sexual orientation, 7% by religion, 6% by disability and 1% were transgender hate crimes.
New statistics published this week by the police demonstrate that post-referendum hate crime soared, in some areas by as much as 100% in some areas.
Police forces across the UK are ramping up intelligence gathering and putting protection in place for vulnerable communities ahead of a projected spike in hate crime when Theresa May triggers Article 50 next month.
Hate crimes on social media are also to be targeted in a £250,000 project by Cardiff University experts focusing on Brexit.
They aim to develop a monitoring tool to help police and government officials curb cases on websites like Twitter.
Ukip leader Paul Nuttall has claimed the officially recorded spike in racist attacks following Britain’s Brexit referendum was “fabricated”. Mr Nuttall told The Independent that such incidents had been “overblown” in an attempt to tarnish the Leave campaign’s victory.
