A spokesperson for the Government Chief Whip said:

“Following a complaint made to the Metropolitan Police this evening, we have removed the Whip from Julian Knight MP with immediate effect.”

UPDATE: Julian Knight responds, saying he has not heard anything from the police or the whips, though will recuse himself from parliament in the meantime:

“I have heard nothing from the police, the Whips Office or Parliament’s Internal Grievance Service, or been the subject of any investigation by the latter. Nor have I ever been warned or spoken to by the Whips office about any allegations of misconduct.

I believe their withdrawal of the whip is wrong and unjustified. Some months ago I accepted the resignation of a staff member following a full enquiry into his conduct regarding House of Commons security issues and, separately, allegations of bullying against him.

Subsequently, I have received what my lawyers advise are explicit threats involving blackmail as well as being at the centre of a campaign of rumour and innuendo. All matters are now with my lawyers and I will be recusing myself from Parliament until the matter is resolved.”
