Munira Mirza, Boris Johnson's long-term political advisor and close ally has quit Downing Street in protest of the Prime Minister's recent Jimmy Savile slur.
Ms Mirza, who has worked alongside Boris Johnson for 14 years, was once described as the woman who inspired the Prime Minster the most, alongside his grandmother.
Described by Boris Johnson as "hip, cool, groovy and generally on trend", the former head of policy had an unusual rise to the top of the Tory party.
