Davina McCall, Mariella Frostrup, Annie Lennox, Richard Wilson and Meera Syal are among the big names launching a new poverty campaign today, the fifth anniversary of Nelson Mandela's Make Poverty History speech in Trafalgar Square.
In a campaign video released today (click here to watch), the celebrities invite people to show their support for a new law that would commit the UK to spend 0.7% of national income on development assistance, by signing up to www.GlobalPovertyPromise.com
The celebrities use the video to highlight how small 0.7% is - yet how much of a difference it will make to lives in the developing world.
