Bath MP Don Foster is the latest politician pledging to do a shift at the Abbeys Assembly Inn, run by Bath brewery Abbey Ales. His shift has been scheduled for Thursday 22 December at 3pm.
Abbey Ales managing director Alan Morgan said: "Don has always been very supportive of Abbey Ales and Bath's pub trade in general.
"Issues such as record levels of red tape and beer tax need addressing if we are to help protect this great British institution and promote responsible drinking - our MPs can help make that happen."
