Asked if he would have liked a better education, he said: "Yeah, 100 per cent. But in school I never learned anything. I didn't even know how to read or write. Out of school I learned reading and writing, everything, on my own. I would read signposts and texting on phones helped. I managed to get there but it would be nice to have a full education. I sacrificed everything because I always believed I'd become world champion. I said to my dad: 'This is what I want to do,' and he always supported me."
Peter Fury, who had a run-in with Parker's promoter David Higgins in a press conference in London at the start of the week, was happy to allow his son to leave school. He himself threw himself into education for the first time when sent to prison. Peter was jailed twice - the first time in 1994 when he received a 10-year sentence for dealing in amphetamines.
Peter said: "Our culture [as Travellers] has always said it's my responsibility as a father to look after my family. So when your sons get going they are on the way to looking after their wives and children. If he liked school I'd have left him in there."
Peter was jailed a second time in 2006 on a money-laundering charge and needed a special visa to enter New Zealand for Hughie's first scheduled fight against Parker in May. The fight never took place because of a back injury to Hughie. Instead, the pair are set to fight in the Englishman's home town.
Hughie, asked about his feelings when his dad was sent away for a second time, said: "It was never easy not having your dad around - but that was really hard. That second time he was in jail for two years. I visited him every week in Manchester prison and he was always asking about my fights and giving me advice.
"I remember him coming out of prison both times. The first time we were in Lancaster staying with granny and grandad. When we came into the house we heard someone playing the saxophone. It was my dad, in the front room. We weren't expecting him to be home so it was unbelievable. He really has been through bad times and it was horrible seeing your dad going in and out of prison."
Once in jail, Peter decided to make the most of it, saying: "I thought: 'I'm not going to be like most inmates. I'll educate myself'.
"I took English courses, literature, writing and business. I passed 11 exams which had nothing to do with prison. They were outside colleges who would come in when you wrote their exams. My writing wasn't so neat but my ideas were good."
