Kelvin MacKenzie, a former editor of The Sun newspaper, has offered "profuse apologies to the people of Liverpool".
Mr MacKenzie oversaw the paper in 1989 when it ran a story entitled "The Truth", blaming fans for the Hillsborough disaster.
''I too was totally misled", the Telegraph reported him as saying.
"Twenty three ago I was handed a piece of copy from a reputable news agency in Sheffield in which a senior police officer and a senior local MP were making serious allegations against fans in the stadium.
''I had absolutely no reason to believe that these authority figures would lie and deceive over such a disaster.
''As the Prime Minister has made clear these allegations were wholly untrue and were part of a concerted plot by police officers to discredit the supporters thereby shifting the blame for the tragedy from themselves".
Mr MacKenzie added that at the time he published "in good faith" and was sorry he was wrong.
Solicitors acting for 20 of the families said they were "appalled to see the shambles in South Yorkshire Police" following the inquest.
With the force facing legal action from the families of the Hillsborough victims, ITV News looks at the web of lies which led them here.
