• Time to reset: more brilliant ideas to remake the world

Ever since I was a boy, it was my dream to become a policeman. Growing up in Toxteth, Liverpool, amid the riots of the 1980s, it must have seemed crazy: black gay scousers from working-class estates didn’t go into the police.

I joined Greater Manchester police three months after 9/11. From training, through to my transfer to the Metropolitan police in London, racism blighted my career. I fell ill with depression, and challenged the police in the courts. The Metropolitan police was found to have harassed, victimised and discriminated against me, because of my sexuality and the colour of my skin. I was then forced out after 11 years’ service.
