CAMPAIGNERS called on Prime Minister Tony Blair to act over the world's water supplies as they set up a stall in Weymouth town centre.

One dressed as Mr Blair and bathed in dirty water as shoppers were invited to sign a petition.

The protest was held on International World Water Day which aims to raise awareness of the plight of millions without access to clean water.

Members of the Weymouth branch of the World Development Movement say it is a political as well as a geographical issue and that ordinary people can make a difference.
