Men and women will be given different views of the interactive advert to highlight the gender discrimination faced by some of the world's poorest girls.

The ad, which will be displayed on a bus stop in London's Oxford Street from February 22, uses facial recognition software to decide whether a man or woman is standing there.

Women and girls are shown a longer 40 second version, whilst men and boys will be blocked from viewing the advert to highlight the plight of girls across the world.

The ad has been created by charity Plan UK as part of its Because I Am a Girl campaign, which wants to see young women in developing countries to have more choices about their lives.

Plan UK points out that millions of girls across the globe are being denied the right and choice to have an education...

The charity's chief executive officer, Marie Staunton, says:

"This ad is a deliberate attempt to raise public debate on this issue.

"...we're not giving men and boys the choice to see the full ad on this occasion, so we get a glimpse of what it's like to have basic choices taken away..."

The advert will be at the bus stop for two weeks... drawing attention to the Because I Am a Girl campaign that highlights some shocking facts like at least 75 million girls around the world are not in school. 

Plan UK's Because I Am a Girl campaign aims to ensure girls in the world's poorest countries can access quality education. This will in turn move people away from poverty to a future of opportunity.

The charity's campaign is gathering momentum and received a major boost in December last year when the United Nations decided to recognise October 11 as the International Day of the Girl Child.

The event will put a special focus on the rights of girls throughout the world highlighting the facts that educated girls are more likely to to be literate, healthy and survive into adulthood, as well reinvest income back into families and communities...
