Reports of incidents of racist hate speech and xenophobic comments in person and on the internet have increased massively since the UK voted to leave the EU. Immigration emerged as one of the key themes of the EU referendum campaign, with those who backed a British exit arguing the bloc had allowed uncontrolled numbers of migrants to come to Britain from eastern Europe.

The Polish embassy in London says it is deeply concerned by recent incidents of xenophobic abuse directed against the Polish community. Police said offensive leaflets targeting Poles had been distributed in Huntingdon, Cambridgeshire, and graffiti had been daubed on a Polish cultural centre in Hammersmith, London. Both incidents were being treated as racially motivated hate crimes, police said.

IBTimes UK rounds up some examples of racist and xenophobic incidents posted on Twitter.
