Nigel Farage has called for the police to step in after comedian Jo Brand joked about throwing battery acid at right-wing politicians.
In a BBC interview she was asked about the divisions being stoked by Brexit.
She replied: “Certain unpleasant characters are being thrown to the fore and they’re very, very easy to hate, and I’m kind of thinking, why bother with a milkshake when you could get some battery acid?”
“I’m not going to do it, it’s purely a fantasy, but I think milkshakes are pathetic.”
Mr Farage said the comments were an “incitement of violence and the police need to act.”
He was hit with a milkshake by a protester during the European Parliament election last month.
Political commentator Paul Joseph Watson said there would be “breathless coverage” on the comments if Jo Brand were not a lifelong Labour supporter.
On Twitter he wrote: “Imagine if a right-winger had 'joked' about acid attacking left-wing politicians. The media would be apoplectic.”
Activist Femi Oluwole said Jo Brand’s comments were “very irresponsible”.
He wrote on Twitter: “Maybe it would have been fine pre-2016 but there are people who might take her words seriously.”
Mr Oluwole also accused Mr Farage of hypocrisy over comments he made in 2017 that he would “pick up a rifle and head for the front lines” if Brexit were not delivered.
A BBC spokesperson said panellists often say things that are “deliberately provocative” and are “not intended to be taken seriously”.
