Workers from Manchester's Boddingtons brewery travelled to Europe this week in a desperate bid to convince owner Interbrew not to close the plant.
Employees from the Strangeways plant arrived in Brussels to attend a meeting of European trade unions, called to discuss plans by Interbrew to move production of the famous beer out of the city. At the meeting they presented the company with a 3,000-signature petition.
If the company goes ahead with plans to brew the beer in South Wales and Preston, 68 workers will lose their jobs.
The plans are part of a Europe-wide review designed to cut costs in the company's brewing operations, which includes the production of brands such as Stella Artois, Beck's and Bass Ale as well as Boddington's.
An interbrew spokesperson said the company was aware of the petition but had nothing further to add at this point.
