The Home Secretary Priti Patel has been accused of bullying civil servants.

The Cabinet Office is investigating several allegations about Ms Patel's behaviour, all of which she denies.

Sir Philip Rutnam, the Home Office's most senior official, resigned on 29 February, alleging Ms Patel's conduct towards staff included "swearing, belittling people, making unreasonable and repeated demands". Since then, similar allegations have emerged from the Department for Work and Pensions and the Department for International Development.
