Iceland has the happiest gay men in the world and the UK places 23rd, according to a new worldwide survey.

The UK ranked 23rd in the survey out of the 127 countries surveyed, and 15th in Europe. The survey also looked at individual issues, such as how comfortable gay men were doing certain things in public, how accepted they felt, and whether they had experienced specific types of discrimination.

Sixty-four per cent of British gay men said they had not experienced discrimination in work or education as a result of their sexual orientation and/or gender identity.

However nine per cent reported they had been seriously physically assaulted as a result of their sexual orientation and/or gender identity.
