Channel 4 has announced a girls-only version of its fly-on-the-wall show The Secret Life Of Five-Year-Olds – to mark 100 years since women first gained the right to vote.

The one-off special will capture what nine girls “get up to when there are no boys around”, in the classroom and playground.

It will “explore how the girls see themselves and the role of women in 2018 … and what their attitudes are to inequality and fairness”.

A classroom and playground are rigged with cameras and experts watch the action, which is supervised by teachers, from behind the scenes in the TV series.

Commissioning editor Alf Lawrie said: “One hundred years after women’s suffrage, this is an extraordinary snapshot of the outlooks of modern young girls.

“It will be a revelation to see what their playing and games reveal about the opportunities and challenges they face in life.”

Maia Liddell, executive producer at programme-maker RDF, said: “I can’t wait to find out what our group of girls get up to when there are no boys around.

“This is a fascinating opportunity to not only discover what the women of tomorrow think it means to be a girl today, but also how they perceive inequality, and more importantly what they want to do about it.”

This year is the centenary of the 1918 Representation of the People Act, which allowed women over the age of 30, who met a property qualification, to vote.

It was only in 1928 that women achieved the same voting rights as men.
