Colin opened up about his sexuality for the first time in September 2017 during an appearance on a Swedish TV show.
During the interview, the retired athlete said he had to come out to his mum and dad in 2006 after a story emerged in the press.
He said: “I was waiting for them in the kitchen. They walked in and they sat down. My mother could see my face and I was quite distraught. It didn’t phase them at all.
“My mum went: ‘First of all, is the story true?’ And I said it’s true, so it’s not like I can deny it. And then she went: ‘Well, why are people so disgraceful?’ I just realised, I’ve got the best parents.”
