Who most deserves an apology from you, and why?

To John, a really close friend who died last year. I'd love to see him one more time and say, 'Look, I'm sorry I wasn't around enough during your life.'

To my 17-year-old daughter Isabella, whom I described in an interview last year as "keen on maths".

When I was little, this boy would bully my friend and me all the time. One day, on our way home, we held him, put him to the ground and pushed his face full on into this big dog poo, and I’d like to say sorry.

To my kids, for my shortcomings.

To my wife Saadiya, for interrupting too many evenings, weekends and family holidays with work.

The Spice Girls – Mel B, Geri and Emma – who wanted to mark our 20th anniversary, and the fans. It was not something I felt comfortable doing.

To anyone I’ve worked with between 5.30am and 8.30am. I am not a morning person.

Teachers at my school, for being such a smartarse.

To my brother. When he was a small boy, I made him urinate on an electric fence to see if liquid could really transmit electricity.

To strangers. Living in New York, I see individuals every day who are invisible to so many. I want to say sorry that so many of us think their pain and suffering is not our own.

Any sorrys I’ve needed to say have been said already.

To anyone who gets into my car, because it’s such a mess.

My dog, Mr Q, because he has the saddest look when I leave.

Max Levy, a German sprint cyclist who came second behind me a lot.

To all those whose fleeting interaction with me has fallen short of what they’d hoped; the unwitting recipients of my occasional grumpiness.

My kids, for the jokes. Some of them are pretty bad.

Any writer who thinks I’ve ruined their work in performance.

To everyone who has been out with me and had to deal with my lack of emotional maturity.

The trans community because I didn’t use the correct words, but I’ve learned from my mistake.

To Mark Smith, a boy we bullied at primary school. I’ve always felt terrible about it.
