Ellie Goulding criticises the lack of women performing at music festivals

Ellie Goulding has criticised the lack of women performing at music festivals.

In a series of tweets, the singer says she doesn't see many females on line-ups and is proud to be a headliner.

She wrote: "Need to give myself credit sometimes as I've been doing this non stop for over seven years. I don't see many females at these festivals."

A BBC study of 14 events across 660 headline appearances suggests music festivals have been dominated by all-male acts for the past 10 years.

Only 37 headline slots involved all-female acts, while 68 were bands of mixed gender.

Ellie Goulding wrote in her tweet: "Still so proud as a female artist to be headlining and playing festivals around the world every single year.

"Need to give myself credit sometimes as I've been doing this non stop for over seven years. I don't see many females at these festivals.

"Il just keep doing what I do."

This isn't the first time Ellie Goulding has had a go at festival organisers.

In 2015, she criticised Glastonbury for not booking more female artists.

"I got annoyed when Glastonbury had so many men on the line-up," she said.

"I get annoyed when men write degrading songs about women, but women are starting to speak out."

Florence Welch was the first British woman this century to headline the Pyramid stage at Glastonbury when she stepped in to replace Foo Fighters in 2015.

Amended festival line-ups have been circulating on Twitter for the last couple of years, showing how they'd look with all the men taken off.

This one of the early Reading and Leeds Festival bill from January had one act containing a female, although more have been added since then.

Every other act was all-male.

Coachella Festival in California had its first female headliner in nine years this year when Lady Gaga stepped in to replace Beyonce.

The line-up had 168 male acts and 60 female artists.

Michael Baker, of the publication Festival Insights, which runs the UK Festival Awards, told the BBC: "Some festivals do attempt to address gender imbalance, such as Field Day, whose curator recently told me that they failed to book 50% female acts because there simply weren't that many available."
