In a statement, Reform UK said: “These allegations are entirely without foundation.
“The Guardian has produced no contemporaneous record or corroborating evidence to support these disputed recollections from nearly 50 years ago.”
Speaking to reporters after PMQs, a Reform spokesman said Farage denied making the comments that have been attributed to him.
He added that the Reform leader had no plans to sue The Guardian for defamation “at this stage”.
Asked if Farage would condemn the sort of language being attributed to him if he heard it now, his spokesman said: “Yes.”
And he said that if past comments of this nature came to light when someone was seeking to be a Reform candidate they would be ruled out.
But he added that there would have to be “primary evidence” that they had said it.
Conservative leader Kemi Badenoch’s spokesman said the “issue was for Nigel and the Guardian”.
“This is something that happened something like 40 years ago and it is for the leader of Reform to explain, not the leader of the Conservative Party.”
