Â鶹ԼÅÄ

In April last year, the Â鶹ԼÅÄ launched its 50:50 challenge, aiming for an equal number of male and female expert contributors on-air and online.

A year on, the results of last month's data have been revealed and show a big boost in female representation.

Nearly three-quarters of Â鶹ԼÅÄ news and current affairs/topical programmes had an equal number of male and female expert contributors.

Only 27% of 74 English language outlets involved had hit the target initially.

Since then, the number of teams signed up to the project across the Â鶹ԼÅÄ has topped 500 and 57% of those groups, including recent joiners, have reached the 50:50 mark.

Â鶹ԼÅÄ director general Tony Hall said: "It's amazing to see such a remarkable change in just a year - you can see and hear it right across our programming.

"I want the Â鶹ԼÅÄ to lead the way on equality and fairness, and this project demonstrates what can be achieved."

More than 20 external media companies have also signed up to replicate the challenge, including the Financial Times and ABC News.

Some of the Â鶹ԼÅÄ programmes that hit the 50:50 target last month included the Andrew Marr Show, Â鶹ԼÅÄ Breakfast, The One Show, Politics Live and Radio 4's Saturday Live.

There has also been progress from teams such as Sportsday, shown on the Â鶹ԼÅÄ News Channel.

It started with 20% female voices and in April reached 43%, more than doubling its female representation.

Contributors refers to all Â鶹ԼÅÄ reporters, commentators, spokespeople, analysts, academics and case studies featured across Â鶹ԼÅÄ content.

The Â鶹ԼÅÄ's 50:50 Project contributes towards the Â鶹ԼÅÄ's commitment to reach 50% women on-screen, on-air and in lead roles across all departments by 2020.
