Christians from many denominations joined protest rallies in more than 50 cities around the world this weekend, calling on world leaders at the UN Climate Change Conference in Bali to effectively tackle the threat of global warming.

Christian Aid is asking thousands of people to put their best foot forward and join its 1,000-mile ‘Cut the Carbon’ campaign march.

Campaigners bound in chains have set off on a 250-mile march to commemorate the abolition of the transatlantic slave trade.

Christian Aid is looking for volunteers to join the longest ever protest march in UK history.

A march is to take place in two months time, involving the Archbishops of Canterbury and York, to express repentance for the Church of England's complicity in the slave trade.
