Rishi Sunak said a racial slur against him by a Reform UK canvasser “hurts and it makes me angry” and that party leader Nigel Farage “has some questions to answer”.
Campaigners for Mr Farage’s party were recorded making racist comments, including about the British prime minister who is of Indian descent.
Mr Sunak on Friday said: “My two daughters have to see and hear Reform people who campaign to Nigel Farage calling me an effing p***. It hurts and it makes me angry, and I think he has some questions to answer.
“And I don’t repeat those words lightly. I do so deliberately, because this is too important not to call out clearly for what it is.”
Speaking on a campaign visit to a school in Teesside in northern England, he continued: “And as prime minister, but more importantly as a father of two young girls, it’s my duty to call out this corrosive and divisive behaviour.”
The footage, made by an undercover Channel 4 reporter, showed the Reform campaigner suggesting migrants should be used as “target practice”.
Another canvasser described the Pride flag as “degenerate” and suggesting members of the LGBT community are paedophiles.
Mr Farage has sought to distance himself from the comments, saying he was “dismayed” by the “appalling sentiments” expressed.
