Veteran Boris Johnson aide quits as Downing Street adviser

Exclusive: Alex Crowley’s departure comes as sources suggest atmosphere of feuding exists in No 10. A veteran of Boris Johnson’s political campaigns has resigned as a Downing Street political adviser as tensions rise between former Vote Leave members and ex-City Hall factions around No 10. Alex Crowley, who worked on Johnson’s Tory leadership campaign, two mayoral campaigns and wrote a book about him, quit last week after just weeks in the prime minister’s political unit.
