A host of celebrities including Beverly Knight and actor Damian Lewis are lining up to back Christian Aid Week 2006, under the slogan; ëYou Add. We Multiply'.
The week, which runs from 14-20 May will encourage people to add their time, money and voice, and see them multiplied to make an impact around the world.
Music star Beverly Knight, actor Damian Lewis, and former EastEnders' star and Strictly Come Dancing winner Jill Halfpenny are all backing this year's initiative.
The aid agency says that the slogan embraces the heart of Christian Aid's belief that together people can make a big difference and that even the smallest donation can grow to achieve real change.
Music star Beverly Knight said: "Christian Aid is committed and assertive in tackling world poverty and its relative impact on health, economy, and social issues. As an ambassador, I have seen their work first hand. Please help Christian Aid this week to keep empowering those who need their help the most."
Actress Jill Halfpenny said: "Having seen for myself the impressive projects Christian Aid supported after the tsunami in India, I was amazed at how many people could be helped with just a small donation. 'You add. we multiply' makes real sense."
Actor Damian Lewis said: "I've been lucky enough to see for myself in Bolivia some of the work Christian Aid does in campaigning for fairer treatment of the poorest people in south America. I hope people give what they can this Christian Aid Week."
Christian Aid Week first started in 1957 - making it the oldest door-to-door collection campaign in the UK.
Last year, Christian Aid Week collectors and supporters raised more than £14.8 million which was used to support the charity's work in more than 50 of the poorest countries around the world.
More than seven million people get involved in Christian Aid Week with around 350,000 volunteers taking part in door-to-door collections using the famous Christian Aid red envelope.
Hundreds of sponsored events take place across the country. One year, volunteers even transformed their Yorkshire town into a Sri Lankan village.
