Celebrities including pop star Daniel Bedingfield and actors Billy Boyd and Pete Postlethwaite are to join next month's anti-poverty rally in Scotland.
Daniel Bedingfield will be one celebrity taking part
Broadcaster Jonathan Dimbleby and singer-songwriter Billy Bragg are to host stages at the Edinburgh event.
It is expected to attract thousands to the city on Saturday, 2 July.
The rally is aimed at highlighting the plight of the world's poor ahead of the G8 summit of industrialised countries at Gleneagles next month.
Protesters who take part will also be able to see highlights of the London Live 8 concert on big screens.
'Loud and clear'
Richard Bennett, chairman of the Make Poverty History Campaign, said it was time for people to make their voices heard.
"The 2nd of July ... will be the day when the people of Scotland and the UK add their voices to those from Africa, Asia and Latin America to send a loud and clear message to the G8 that now is the time to end the tragedy of thousands dying from poverty," he said.
"As well as the serious messages, the day will have something for everyone, with inspiring speeches from an eclectic and international mix of contributors, interspersed with music from two stages in the Meadows and live links to Live 8 in London."
Protesters are being asked to wear white for the event so they can form a white band around Edinburgh.
Film-maker Richard Curtis, a supporter of the campaign, said: "We have the unique opportunity to be the generation to say that enough is enough.
"Every person forming the white band around Edinburgh will be playing their part in what will be remembered as the day when the world cried out for justice."
