Former Busted star Matt Willis is backing Save the Children's biggest ever appeal for emergency 'superhero' fundraisers, which launches tomorrow.

To mark the anniversary of two emergencies, the cyclone in Burma and the earthquake China, the charity is looking for hundreds of volunteers to become Save the Children superheroes, dropping everything to help raise funds when an emergency hits.

Matt, who was also the winner of the ITV's I'm a Celebrity Get me out of here! show in 2006, is the first superhero to take up the challenge.

Everyone who signs up will receive an emergency tin, not to be opened until the instruction is given.

As soon as the next emergency strikes, before it even hits the headlines, Save the Children will send a red alert text to all their emergency superheroes alerting them to the disaster.

They will be instructed to break open their tins and follow the step by step instructions.

The emergency tin will contain: branded t-shirts, ten top-tips for fundraising, world maps, and a memory stick with videos showing clips from Save the Children's previous emergency responses, and guidelines on how they should get out there fast to raise funds and help save children's lives.

Matt Willis said: "I've taken up Save the Children's challenge to be a superhero in emergencies because they've shown me that anyone can save lives if they want to.

"You don't have to have superpowers to make a difference. I hope that I can relay that message to people so that when they feel moved by an emergency like I know I was during the Burma cyclone and Chinese earthquake last year, that they know that they can do something to help.

People can sign up as fundraisers for emergencies by calling the charity's hotline 020 7012 6400 or going to www.savethechildren.org.uk/givetime.

Save the Children works to give every child their rights, and to stop millions of children dying each year. It focuses on four fundamental rights for children: health, freedom from hunger, education and protection.
