Police are investigating a suspected anti-Semitic attack on a Jewish Brexit Party candidate after a 30-foot swastika was sprayed on his business headquarters.

The incident happened at the London factory owned by Lance Forman, head of Britain's oldest salmon curer H.Forman & Son, late on Tuesday night.

Mr Forman, whose father is a Holocaust survivor, told the Jewish Chronicle: “The fact that we have been targeted in this antisemitic way is quite horrific and sick.

“The police have images of the culprits on CCTV and I sincerely hope they are tracked down.”

Last month, Mr Forman announced he would stand in the upcoming European Elections for the Brexit Party in the London region, praising Nigel Farage as “formidable”.
