The Rt Rev Sheilagh Kesting, Moderator of the General Assembly of the Church of Scotland, will lead over 1000 marchers on the Edinburgh sector of the Christian Aid Cut the Carbon Rally.

The rally is the longest ever protest march in history, bringing thousands of people across the country together to highlight the devastating impact that global warming is having on millions of people worldwide.

The Moderator, along with Daleep Mukarji, Director of Christian Aid, will lead the marchers from Castle Street to the Meadows for a rally on Saturday afternoon.

A star-studded musical line-up will provide a welcome rest for the marchers. Artists include Amy Macdonald, the hotly-tipped Glasgow singer-songwriter, Attic Lights and award-winning saxophonist and rapper Soweto Kinch. Scottish actor Billy Boyd, star of Lord of the Rings, will also play a short set with his band Beecake.

Cut the Carbon is a 1000-mile, 80-day walk from Northern Ireland which began on the 14 July and will end at the London Stock Exchange on 2 October.

Scottish marchers include Angela Rowe from Glasgow, who is married to a trainee minister at Renfield St Stephen's Church in Glasgow and 19-year old Stuart Douglas from Motherwell.
