Sonia Khan, a Treasury media adviser, was escorted by armed police from Downing Street following a confrontation with No. 10's chief strategist owing to her contact with those close to the former chancellor Philip Hammond. Khan, who was Sajid Javid's media adviser was accused of lying about her conversations with Hammond’s former staff member Poppy Trowbridge. These accusations have been filed by Dominic Cummings, who is understood to have found evidence they had been in touch on her personal mobile phone.
Khan was the second adviser working for Javid to be sacked by No 10, leading to suggestions that Javid is becoming increasingly isolated from the core of the Johnson regime.
