The Big Dig Appeal aims to bring clean water and safe sanitation to 134,000 people living in rural Malawi. Strictly Come Dancing champion and actress Camilla Dallerup, and her husband, actor Kevin Sacre, were at Westfield London to kick off the appeal. All money donated to the appeal will be matched pound for pound by the UK Government from the aid budget, helping us to reach twice as many people. Camilla said: "Being a dancer, I know how important clean water is to keep you hydrated. But millions of people don't have this luxury at the turn of a tap. "Helping people get access to clean water and toilets doesn't only improve their health, but also impacts on education and livelihoods. These are simple solutions that make a huge difference, so we're calling on people to dig deep for Malawi today." Malawi is one of the world's poorest countries, with half the population living below the poverty line. Around 20% of the population have no clean water supply, and half the population has nowhere safe to go to the toilet. All money donated to the appeal will be matched pound for pound by the UK Government from the aid budget, helping us to reach twice as many people. Overall, we're hoping to raise £1.2m to bring safe water and sanitation to more than 134,000 people in Malawi. The appeal is being supported by more than 30 UK commercial radio stations, including First Radio and Real Radio stations as well as Bauer’s Kerrang! Radio, talkSPORT and Jazz FM. Also supporting the appeal are celebrities including Rachel Stevens, Sanjeev Bhaskar, Hugh Bonneville, Joe Calzaghe, Biffy Clyro, Lorraine Kelly, Joanna Lumley, Cyrille Regis, John Simm, Denise Van Outen, Tommy Walsh and Kim Wilde. We are offering a unique opportunity to follow the progress in Malawi and see exactly where your money is going. Through The Big Dig blog, you can hear and see directly from two of the communities benefitting from the appeal as they get access to clean water and toilets for the first time. We're using YouTube and Instagram to bring you real-time insights from these communities. Barbara Frost, WaterAid's Chief Executive said: "It can cost as little as £15 to provide one person in rural Malawi with safe water, improved hygiene and sanitation which means the money raised will make a real difference to people's lives. With the UK Government matching every pound, the public's donations will go twice as far." Helping people get access to clean water and toilets doesn't only improve their health, but also impacts on education and livelihoods. These are simple solutions that make a huge difference. Development Secretary Andrew Mitchell said: "Donations to WaterAid's Big Dig Appeal will help communities in Malawi living without clean, safe water or proper latrines to get access to these vital resources that we in the West take for granted. "To support this life-saving work, and in recognition of the generosity of the British public even in times of austerity, I am pleased to announce that the British government will help WaterAid transform the lives of twice as many people by matching pound for pound all public donations to the appeal."
