Cressida Dick - the newly-appointed Commissioner of the Metropolitan Police - is the first woman to lead the force in its 188-year history. Dick's career has been exceptional, but not without controversy. She was gold commander in the control room in the aftermath of the 2005 London bombings and was at the helm when the innocent Brazilian Jean Charles de Menezes was shot dead by police at Stockwell tube station. Her appointment as Commissioner is a comeback of sorts; in 2014 she quit the police to take up a job at the Foreign Office.
