Boris Johnson’s Mr Fixit - a Deputy Chief of Staff - brought in to steady the ship at the height of the "Partygate" allegations. Described as politically astute and determined for the Conservatives to win the next election, Canzini's career in the Tory party began in the 1980s. He's a long-standing Brexiteer who's worked alongside former Conservative leader, William Hague, and is a close ally of the Tories’ election guru, Sir Lynton Crosby. His critics worry he is pushing the Prime Minister further right on things like asylum seekers and trans issues.

Mark Coles explores the life and career of the man who goes by the name DC Grumpy on social media, has a profile picture of Darth Vader and once sported a David Cassidy-style haircut.
