The four men behind the nationwide Brexit billboard phenomenon finally reveal their identities – in the pub where it all began

The Birdcage pub in Stoke Newington, north London, seems an unlikely birthplace for a rebellion. On a midweek afternoon, the bar is almost empty. Spring sunshine streams through the windows; Spandau Ballet provide a gentle soundtrack; black-hatted men from the local ultra-Orthodox Jewish community pass by outside.

The only customers are four men sitting at a table in an alcove. It was at this spot, more than five months ago, that this group of friends came up with an idea born from their collective despair over the “lies, lunacy and hypocrisy” of the Brexit process.
