More than 100 parliamentary candidates have signed the I'm Backing the Pub pledge during the last week, in a surge of support for the trade.
The British Beer and Pub Association's (BBPA) campaign aims to promote the positive aspects of the pub, lower tax and burdens on pubs and beer and restrict new legislation in favour of enforcing existing laws more effectively.
The campaign has now been signed by 419 parliamentary candidates.
"It is clear that there is a growing momentum for the pub in this Election campaign," said BBPA chief executive Brigid Simmonds.
"Candidates from all parties and all regions understand the importance of the British beer and pub industry to their own local economies, but they are rightly concerned about the state of the industry.
"In the last two years, beer tax has increased by 26% whilst over 4,000 community pubs have closed at the cost of more than 40,000 jobs.
"Each of the main political parties, for the first time ever, have come out and said they support the pub in their manifestos.
"But we need to hear more details of what they propose. It is time now for all the parties to listen to their own candidates and say exactly how they intend to back the pub."
