Farage was left with milkshake dripping down his suit during a walkabout in the city on Monday. Crowther said he threw the banana-and-salted caramel Five Guys shake to protest the politician's "bile and racism."
Farage's Brexit Party is leading opinion polls in the contest for 73 U.K. seats in the 751-seat European Parliament. Milkshakes have become an unlikely political weapon in Britain. Other right-wing candidates including far-right activist Tommy Robinson have also been pelted with milkshakes during the election campaign.
