However, the inspector recommended that the north side of the airport be removed from the green belt allowing the land to be developed in future.

North Somerset Council has welcomed the report saying it will help protect the surrounding countryside.

The airport has said it will re-submit proposals for expansion after 2011.

Councillor John Crockford-Hawley, of North Somerset Council said the report supports the council's wish to balance economic and environmental needs.

"Substantial airport growth with only minimum regional highway investment would be disastrous for the already overburdened surrounding villages," said Cllr Crockford-Hawley.

A spokesman for the airport said it will continue to seek further evidence that developing the north side for car parking is feasible.

"Bristol International will continue to carry out a strategic review of car parking options, so that a suitable and practical solution can be developed to meet the future needs of passengers parking at the airport," said Alan Davies, Head of Planning and Development at Bristol International Airport.

The report by Mr Richard Poppleton, an independent inspector appointed by the Secretary of State, follows a four-day local plan public inquiry held in July.
