Beyonce and Britney Spears songwriter Carla Marie Williams says she wants to encourage more women to come forward to work in the music industry.

She is the founder of Girls I Rate, which has chosen 100 young women to perform their own music to a panel of industry experts at an event in King's Cross, London.

Singer Lily Allen, one of the event's hosts, said: "There are more girls getting involved in songwriting and production.

"It's brilliant, things are happening."
