A weekly newspaper is petitioning 10 Downing Street as part of a campaign to save its local prison from closure.
The Lincolnshire Echo launched the online petition after it learning that Lincoln Prison could be closed after 140 years and the building used to house illegal immigrants awaiting deportation.
The closure plan would mean the loss of around 500 jobs with 750 prisoners sent to various sites outside the county.
A review of the prison site is being undertaken by the Ministry of Defence with a decision on its future expected to be made soon.
Editor Steven Fletcher said: “The possible closure of Lincoln City is a huge story in this city. The prison provides direct and indirect employment to at least 500 people.
“The public were unaware the Ministry of Justice was carrying out a review and that Lincoln Prison’s future was up in the air.
“We’re going to fight this hard. The Echo has to lead the way in standing up for the best interest of the city. We don’t want it closing, and even downgrading the prison would cost hundreds of jobs. We want it to remain as a Category B prison.
“What we want to do with this campaign is make Government listen, before they make an irreversible decision that would be devastating for the local economy.
The paper’s online petition which has been lodged on the Downing Street website calls for a full public consultation before the prison is closed.
Lincolnshire County Council is also opposing the move, with chief executive Tony McCardle arguing that the prison attracts £11m into the local economy.
He said: “This will put an incredible burden on local businesses, the probation service and local solicitors. It would be a huge and unnecessary blow at a crucial time when times are already very hard.
“Around 500 potential job losses is significant in that we do not have many employers in Lincolnshire that employ that many people. With so many jobs on the line, anything like this is bound to have a knock-on effect.
“Any significant job losses are regrettable. This isn’t just going to be a short-term problem, but a long-term one and that is of great concern.”
