Nigel Farage had a milkshake thrown at him during a Brexit Party 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.
Anti-far-right activists have regularly adopted the tactic of throwing milkshakes as a form of protest at candidates.
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.
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.
