Judge Mrs Justice Lang ruled Boris Johnson, chairman of TfL was acting lawfully when he blocked the Core Issues Trust’s proposed advert because it would ‘cause grave offence’ to those who were gay.

The posters read: ‘Not Gay! Ex-Gay, Post-Gay and Proud. Get over it!’ They were a response to a bus poster campaign by gay rights group Stonewall, which carried the message: ‘Some people are gay. Get over it!’

Justice Lang gave Core Issues Trust permission to take its case to the Court of Appeal, citing concerns over issues of freedom of expression as her reason.

A Core Issues Trust spokesman said: ‘We are particularly concerned about the fact ex-gay minorities are not recognised in the legislation of the Equality Act 2010.’
