Wellingborough MP Peter Bone has called on the Prime Minister to speed up the decision on a £50 million retail development in Northamptonshire.
Last month the Government delayed the decision on whether or not to approve the Rushden Lakes development.
The proposals, which include shops and leisure facilities, have already been agreed by East Northamptonshire Council but the final decision rests with the Secretary of State for Communities and Local Government.
Speaking in the House of Commons, Peter Bone MP asked the Prime Minister:
"I've never known of a development that has so much public support. Could the Prime Minister use his best efforts to ensure that the outcome of the public inquiry is announced as soon as possible?"
In response, David Cameron said:
"I know my honourable friend campaigns vigorously for his constituents and for local businesses and for job-creating developments like this one.
"As I'm sure he is aware, I'm not able to get involved in specific planning decisions but I understand that a decision on this application will be made as soon as possible."
Wellingborough MP Peter Bone has criticised the decision to close HMP Wellingborough.
The Conservative MP told Parliament the closure of the prison in his constituency could mean the loss of up to 600 jobs. He described it as a "good improving prison" and said it was becoming more cost effective.
