Outburst comes after anti-racism campaigners disrupt event in South Yorkshire and are escorted out

The Reform UK leader Nigel Farage has accused “left-wing” teaching unions of poisoning the minds of young people “against everything this country has ever stood for”.

His outburst came after anti-racist campaigners disrupted a Reform UK event on Tuesday where Farage was due to announce the party’s candidate for the forthcoming mayoral election in Doncaster.
