People with non-visible disabilities have told the BBC they face discrimination in restaurants and cafes when they present a card addressing their condition and the need for an accessible toilet.

John McGeachy, from Age UK London, said: “People with health conditions, older people, disabled Londoners, pregnant women, people with young families, we’re all human, so we all benefit from more public toilets.”

He said the availability of lavatories can determine whether people feel able to leave their homes.

“We’ve known provision has been declining in London and across the country for a long time, but this new report means we have a much clearer picture about the scale of decline.”
