The Article 50 letter was written in Downing Street by Nick Timothy and only shown to David Davis the day before it was delivered to Brussels. ‘DD couldn’t tolerate that he didn’t know exactly what was in it or when it was going to be,’ a Downing Street official recalled. A DExEU source said, ‘Nobody saw the Article 50 letter until twenty-four hours before it was sent. DD kept asking. Bridges kept asking. We knew Hammond wouldn’t be shown it. He kept asking as well.’
