Lancashire brewer Daniel Thwaites has appealed to its local MPs to back calls for a freeze in beer tax.
Managing director Peter Morris has written to MPs including Blackburn's Jack Straw and Ribble Valley's Nigel Evans urging them to sign an Early Day Motion to show support for the pub trade.
The motion supports a campaign led by the British Beer and Pub Association, the Campaign for Real Ale and the Society for Independent Brewers to freeze beer duty and scrap the beer duty escalator ahead of March's Budget.
"I hope the MPs will listen to our concerns, and back this motion in Parliament, as beer and pubs are an absolutely vital part of the Lancashire economy," said Morris.
"Over the past year Thwaites have invested over £3 million in its pubs and hotels in the area, with plans to invest a further £2.5m in the coming year, creating local jobs.
"The current Government policy is counterproductive, as it is shutting down pubs, and costing jobs."
