A national demonstration will take place at Westminster on Monday (30 June) to complain that a third of the government's proposed eco-towns are being backed by developers that have associations with supermarkets.

Protesters campaigning against the 'Tesco-isation of Britain' are outraged that five out of the 15 planned eco-towns involve organisations with a history of developing land for Asda and Tesco.

Between 5,000-15,000 low carbon homes are to be built in each proposed eco-town. Tesco is currently bidding for an eco-town at Hanley Grange in Cambridgeshire and The Co-operative Group is set to own the site in

Pennbury, Leicestershire.
