Government and public pressure could still keep Colman's Mustard in Norwich, a local MP has told the BBC.
At the beginning of last month, Colman's Mustard's owner Unilever said it could shut its factory in Norwich after Britvic revealed plans to close its shared manufacturing operation.
Norwich North MP Chloe Smith met with Business Secretary Greg Clark last night, along with a Norfolk delegation from the New Anglia Local Enterprise Partnership (LEP).
Ms Smith said Mr Clark told them he would be talking to Unilever to try to save the 113 threatened jobs.
She said: "I want them [Colman's] to stay in Norwich. We have the support of the business secretary, who is working with Unilever to look for feasible options to stay in Norwich."
Ms Smith said it was possible that "research and development funding" could help support Colman's.
"The government has shown it is willing to invest where there are exciting industrial opportunities," she said. "Mr Clark will be talking to Unilever this week and press the benefits of staying in Norwich."
She praised the public support for Colman's, saying this also helped put "pressure" on Unilever.
