Nigel Farage has challenged the contestant’s racist insults

The BBC contacted Mr Parker about Farage’s comments, but he did not wish to comment.

Channel 4 News said it was committed to “accurate and impartial journalism”, adding that it first met Mr Parker at the Reform Party’s UK headquarters and did not pay him any money.

Mr Farage was then asked about other comments made by UK Reform Party candidates.

Edward Oakenfull, who stands in the Derbyshire Dales, books Offensive posts on social media about the IQ of sub-Saharan Africans. Ockenful told the BBC that his comments were “taken out of context”.

Robert Lomas, a candidate in Barnsley North, reportedly said blacks should “get off”. [their] “Lazy people” and stop acting “like savages.” The comments were published by The Times on June 8, with Reform claiming at the time that they were “quotes taken out of context” and that it needed more time to respond.

Lesley Lilly, who was standing in the Southend East and Rochford area, reportedly described people arriving on small boats as “scum” and added: “I hope your families get robbed, beaten up or attacked.”

Farage said he disavowed the candidates in question, adding: “I want nothing to do with them.”

“There are people in all parties saying bad things and wrong things,” he said, suggesting this was partly a result of having to find candidates quickly after the prime minister’s surprise call for a general election in July.

Mr Lilley is no longer a Reform UK candidate in the constituency on the party’s website, but Mr Ockenfull and Mr Lummes are on the list.

The BBC contacted the Islah Party to confirm whether the party has officially withdrawn its support from the three candidates.

However, it is too late to prevent them from appearing on the ballot.

Green Party co-leader Adrian Ramsay was also asked about comments made by some of his candidates regarding the conflict in Gaza, including one who compared Hamas to French resistance fighters in World War II.

Mr Ramsay said he did not support those views, adding that any concerns would be “properly investigated through the correct channels within the party” – saying those channels were separate from the leadership.

“Unfortunately, all parties have candidates who were chosen in these elections but are no longer able to move forward,” he said.
