The broadcaster initially said Mr Lumdsden’s “88” tattoo was a reference to 1988, the year of his father’s death.
But 66-year-old Trevor Lumsden reportedly told the Daily Mail he was Mr Lumsden’s father and had not seen his son “for some years”.
AETN UK said today that following an investigation, it had “made the decision not to broadcast any further episodes of The Chop” and was reviewing its internal procedures.
“A contestant’s tattoos included symbols that could be connected to far-right ideologies and could cause offence,” it said.
“We sincerely apologise for that and we are sorry that our processes did not prompt further investigation at an earlier stage.
“The contestant continues to strenuously deny that he has, or ever had, far-right leanings.
“AETN UK and Sky History stand against racism and hate speech of all kinds.”
