The Co-operative Group wants to build a 15,000-home eco-town on land it owns between Great Glen and Stoughton, a plan which was shortlisted by the Government in April last year.

Two new images were released on Friday, a bird's eye view and a close-up of a street scene.

It follows the release of three other Co-op artist's impressions in January which depicted watercolour-esque designs showing an expansive public square with allotments, a play area and Continental-style outdoor seating area.

The new aerial shot shows a number of glass-roofed properties with a park and land in the distance.

Co-op has issued the images to co-incide with its 'information guide' which summarises the proposals contained in the group's 'masterplan vision document' published on October 9 last year.

Ruairidh Jackson, head of planning and property strategy for the Co-op Group, said: "The eco-town offers an alternative to the piecemeal development of new homes being built here and there on the edges of existing communities, increasing the strain on existing infrastructure and services while lacking the scale required to fund essential infrastructure."

Dr Kevin Feltham, chairman of the Campaign Against the Stoughton Co-op Eco-Town (Cascet), said: "It's another piece of flim-flam from the Co-op. Once again there's no information about hospitals or other community facilities – I wish they would hurry up and get on with releasing that information."

The Department for Communities and Local Government, which is set to rule in the spring or early summer on which proposals go forward, has extended the eco-town consultation period until April 30.

Cascet is holding a musical fundraising evening on Saturday night to bolster its war chest.

The classical soiree is taking place at the 800-seat hall of Leicester Grammar School in Great Glen from 7.30pm.

It will feature a variety of songs from musicals and more classical pieces from young musicians and professionals who have given up their time for free.

Tickets cost £10 (£5 for children) and are available from Ireland and Longhill in Station Street, Kibworth, Great Glen Parish Council Office in Church Road or Great Glen Post Office in Stretton Road.
