Downing St faces unfair dismissal claim after aide frogmarched out of her job by armed police

Sonia Khan, former adviser to the Chancellor of the Exchequer, who worked for both Philip Hammond and Sajid Javid, was accused of passing information to Hammond while serving Javid – a claim she refutes.

It is understood that Javid himself was not consulted before Khan was sacked.

The former aide claims that proper dismissal procedures were not followed, she was not given the right to representation, and she was unnecessarily humiliated by the method of her removal from her place of work. She is making an additional claim of discrimination.

While legal experts have predicted the case will be settled out of court to save embarrasment to senior government officials, if it did make it to an employment tribunal, Boris Johnson himself could be called to testify as employer.
