Spice Girls beauty Melanie C has revealed that she's backing a new clean water campaign being spearheaded by consumer product company Procter & Gamble. 

The clean water initiative comes in the form of purification sachets that can make dirty water drinkable, and the project took her across the world to Africa, where she witnessed the positive impact the sachets have been having so far. 

Speaking about her journey and experience in the country, Mel C explained: "I've been on charity trips to Africa before. They can be harrowing, but this one was really positive and inspiring. Already it's changing people's lives."

"When we first arrived, three of the girls took us down to the local water supply, which is basically a big lake shared with animals, so that water can be very dangerous. Using the sachets, in half an hour the water goes from back to clear. We drank it as well - it's completely and utterly safe."

Customers who purchase any Procter & Gamble product from superstore ASDA up until March 19 will help the campaign as P&G has vowed to donate 1 day's clean drinking water per item bought.
