Nigel Farage has been drenched by a milkshake during a walkabout in Newcastle City Centre.
The Brexit Party leader had to be led away by security as a person was dragged away by a Police Community Support Officer.
Farage fumed at his security staff: "How did you not stop that happening? It's a complete failure."
Paul Crowther, 32, from Throckley, Newcastle, said it was a £5.25 Five Guys banana and salted caramel milkshake.
He said: "I didn't know he was in town, I thought this is my only chance."
Mr Crowther said he saw there was a Brexit Party event in the city centre, thought it was an MEP and then saw Mr Farage.
UKIP 'rape joke' candidate Carl Benjamin has milkshake thrown at him again
He explained: "It's a right of protest against people like him.
"The bile and the racism he spouts out in this country is far more damaging than a bit of milkshake to his front."
Farage tweeted: "Sadly some remainers have become radicalised, to the extent that normal campaigning is becoming impossible.
"For a civilised democracy to work you need the losers consent, politicians not accepting the referendum result have led us to this."
It's the latest in a string of dairy-based protests.
Last Friday, Ukip candidate Carl Benjamin’s tour got off to an ignominious start when he first had kippers thrown at him, before a milkshake was hurled in his direction in Truro, Cornwall.
Squirming Brexit Party chief repeatedly fails to say if party takes foreign cash
The following day a UKIP battle bus was hit with a parking ticket and had milkshake thrown over it during a party rally in Plymouth.
Milkshakes have also been used as missiles against MEP candidate Tommy Robinson, the former English Defence League leader whose real name is Stephen Yaxley-Lennon.
Robinson, who is standing as an independent in the North West of England, had milkshakes thrown over him twice in as many days in Bury and Warrington.
