´óÏó´«Ã½

In April last year, the ´óÏó´«Ã½ 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 ´óÏó´«Ã½ 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 ´óÏó´«Ã½ has topped 500 and 57% of those groups, including recent joiners, have reached the 50:50 mark.

´óÏó´«Ã½ 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 ´óÏó´«Ã½ 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 ´óÏó´«Ã½ programmes that hit the 50:50 target last month included the Andrew Marr Show, ´óÏó´«Ã½ 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 ´óÏó´«Ã½ News Channel.

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

Contributors refers to all ´óÏó´«Ã½ reporters, commentators, spokespeople, analysts, academics and case studies featured across ´óÏó´«Ã½ content.

The ´óÏó´«Ã½'s 50:50 Project contributes towards the ´óÏó´«Ã½'s commitment to reach 50% women on-screen, on-air and in lead roles across all departments by 2020.
