The allotments are in the heart of the Olympic Park

Manor Garden Allotments in Hackney Wick, east London, was to be moved to Marsh Lane in Leyton but planners refused the application.

London Development Agency (LDA) has submitted a revised plan, which has pushed back the evictions until July.

Plot holders are campaigning to save the 81 allotments, which are on the site of the main Olympic concourse.

'London asset'

The Green Party is supporting their fight and has called for the evictions to be halted until an alternative site is secured.

The revised planning application is expected to come before Waltham Forest Council's planning committee in May.

Hopes for an April move were dashed and the LDA said plot holders could remain in place until July while the application goes through.

However, the agency was inviting allotment holders to begin handing over their plots ahead of the move.

Each plot holder is entitled to �850 in compensation for the move.

The LDA has promised to move them back to a new and improved site after the Games.

"We have been working with the allotment holders for almost two years to find a suitable alternative site," an LDA spokesman told the BBC News website.

"After the games they will move back to a landscaped site which could be bigger."

Julie Sumner, a Manor Garden Society spokesman, told the website: "We're still not convinced about the arguments for moving us.
