Tutu, the international human rights and peace activist and former Archbishop of Cape Town, is the face of international development charity World Vision's latest media campaign.
Tutu will appear in adverts on London-based television stations, in the press and on posters on the London Underground from 21 April to 2 May, calling for people to sponsor children in poor communities overseas.
"Inside us all is something strong enough to change the world," says Tutu in the advert. "To refresh those without water, to care for the sick - one small act of goodwill."
James Mooring, head of consumer marketing at the charity, says: "We feel very privileged that Desmond Tutu is lending his support. This is a man who has dedicated his life to fighting injustice in all its forms, not only at home in South Africa, but around the world."
- BBC football commentator Jonathan Pearce ran last week's London Marathon for the Lily Foundation. The charity was set up in memory of his eight-month-old niece, who died from Mitochondrial disease, a cell abnormality that affects one in a thousand babies. He was joined by Kate Lawler, the television presenter, DJ and winner of Big Brother in 2002, who was wearing only underwear designed by Ann Summers to raise money for the Cystic Fibrosis Trust. Fellow TV presenter Ben Fogle ran the race with the target of raising £5,000 for the RNLI. Pop singer Ronan Keating ran for Cancer Research UK and raised more than £14,000. Actor and Britain's Got Talent panel member Amanda Holden ran to raise more than £6,000 for the Born Free Foundation.
Save the Children has received more than 12,000 baby hats after chat show host Paul O'Grady mentioned the charity's knitting campaign on his eponymous show on Channel 4 last month. The charity says a woolly hat can mean the difference between life and death for newborn babies because they can't regulate their own body temperatures.
Charlie Dimmock, presenter of ITV1's River Walks, is supporting CSV's Action Earth campaign by encouraging people to sign up to volunteer in local environmental projects.
The Calendar Girls, the members of the Women's Institute who stripped off for a calendar to raise money for Leukaemia Research in 1999, are featuring on boxes of chocolates sold by retailer Asda to raise money for the charity. Chocolatiers Whitakers and Asda will make donations of 20p each for every box sold.
Kate Adie, the former chief news correspondent for the BBC who has reported from war zones around the world, became a patron of international children's charity Hope and Homes for Children earlier this month.
Former UN commander Mark Cook, the founder of the charity, was with BBC journalist Martin Bell when Bell was seriously injured by shrapnel during the war in the former Yugoslavia in 1992. Adie, who now presents From Our Own Correspondent on BBC Radio 4, was sent out to cover the war as Bell's replacement, and she and Cook became firm friends. Cook went on to set up Hope and Homes for Children, which Adie has supported ever since.
"Kate has long been a committed supporter of our work," says Rick Foulsham, chief executive of the charity. "Having covered the war in the former Yugoslavia and reported extensively from Rwanda and other countries where we have programmes, Kate has a keen understanding of the challenges faced by the children and families we support."
