On 14 June, a short email popped up in the inboxes of all Financial Times editorial staff. It came from the paper’s style guru and announced tersely: ‘The out campaigners should be Brexiters, not Brexiteers.’ As usual for the FT’s style pronouncements, the memo did not lay out the reasoning behind the decision, but it followed a discussion among editors over whether the word ‘Brexiteer’ had connotations of swashbuckling adventure.
