Flagship BBC One topical debate show Question Time will be coming to Grantham next month.
The show chaired by David Dimbleby will be broadcast live from the Meres Leisure Centre on Thursday, February 1.
Potential audience members will be asked to come up with two questions to be considered for the programme.
Tickets are limited and usually over-subscribed.
Successful applicants will be contacted between Monday 29 and Wednesday, January 31.
Councillor Ian Selby, from Fighting 4 Grantham Hospital campaign group, has encouraged his fellow campaigners to apply.
He said: “Let’s get as many of our campaigners in the audience as possible.
“This would be a great opportunity to highlight our fight for restoring our A&E 24/7.
“Let’s go up a gear with the campaign.”
