Angela Rayner caused a bit of a stir a few weeks ago when she rocked up at the Glyndebourne opera festival. The stiletto-sporting socialist made much capital out of her trip after Dominic Raab mocked her for picking a Mozart opera over the RMT picket line, enabling her to pose as a victim of Tory sneers and classist smears. But it seems that Glyndebourne made the right-on Rayner and others feel right at home, judging by the latest innovation at the Grade II listed manor house.

Now gender-neutral toilets have been introduced at the venue in question, replete with the requisite sign that left some older attendees baffled. Along with the traditional pictogram for male and female toilets is a half-skirt, half-trousers symbol to denote those who do not identify as either gender. Asked about the blue stalls plaque, a Glyndebourne spokesperson told Mr S: ‘We’ve adopted a widely recognised symbol to indicate gender-neutral toilets, which we have introduced at Glyndebourne to ensure everyone feels welcome.’

Talk about an aria of expertise…
