More than 400 would be MPs have now signed up to the British Beer & Pub Association’s (BBPA) I'm Backing the Pub campaign.
The trade organisation said that since Monday of last week, 100 parliamentary candidates had signed up to the pledge.
The pledge calls on government, industry, local authorities and others to work together to support British pubs as part of efforts to enhance community life and promote economic recovery.
Brigid Simmonds, chief executive of the BBPA, welcomed the support. She said: “In the last two years, beer tax has increased by 26 per cent whilst over 4,000 community pubs have closed at the cost of more than 40,000 jobs.”
The news comes as the Liberal Democrats stated they would reform the beer tie, insist on a Competition Commission investigation into pub ownership, ban cheap supermarket alcohol and review the beer duty escalator if they got into power on the 6 May.
