A woman who threw a banana milkshake over Reform Party leader Nigel Farage during this year’s British election campaign has been handed a suspended sentence.

Victoria Thomas Bowen’s 13-week prison sentence was suspended for 12 months after she admitted to assault, PA Media said, meaning she will not go to jail unless she commits another criminal offence in that time.

Westminster Magistrates’ Court ordered the 25-year-old to pay £150 ($A299) in compensation to Farage and complete 120 hours of unpaid community work, the BBC reported.

Bowen launched the milkshake at Farage outside a pub in Clacton-on-Sea, south-east England, while he was out campaigning ahead of the July 4 British election, leaving the right-wing politician drenched.

It wasn’t Farage’s first encounter with a banana milkshake. He was also attacked with the beverage in 2019 when he was out campaigning in Newcastle, northern England.

Farage, who helped champion Britain’s departure from the European Union, won the seat of Clacton at the election.

Bowen pleaded guilty to assault by beating and criminal damage at a court hearing in October, also admitting to causing damage to the jacket of Farage’s security guard.

Her lawyer, Andrew Price, previously said Bowen decided to plead guilty because she had suffered threats.
