The Keychange pledge for gender equality in the music industry has reached the milestone of 500 signatories.

Launched in the UK in 2017, the initiative aims to achieve at least 50% representation of women and gender minorities on line-ups and within record labels, publishers, orchestras and more through tailored objectives.

As well as signing up UK groups such as BBC Proms, the Barbican and Aldeburgh Festival, the pledge has also attracted support in China, Latin America and Australia.

The 500th signatory was EBU Music – part of the European Broadcasting Union, which produces the Eurovision Song Contest.
