Bermondsey & Old Southwark MP Neil Coyle joined local members of the Campaign for Real Ale (CAMRA) on Saturday for a tour of pubs in the constituency.
The parliamentarian's pub crawl began at the China Hall and the Mayflower in Rotherhithe.
A year ago we reported on plans to knock down the much-loved pub and replace it with a 10-storey block of flats.
After swift action by local people, the pub was registered as an asset of community value (ACV) under the Localism Act.
The pub's owners withdrew their planning application and the threat to the pub's future seemed to have receded – but with the current operator's lease coming to an end, there are now fears that a new lease won't be granted at an affordable price.
"While the building might still stay here, we're concerned to make sure that it remains as an operating pub," Steve Silcock, chair of the South East London branch of CAMRA, told the SE1 website.
"We want to make sure that the owner of the building does the right thing and agrees a new lease with the current operator, who is running a fantastic pub – with a massive commitment to original live music – and that needs to continue."
