Sir Philip Rutnam’s statement in full

I have this morning resigned as permanent secretary of the Home Office. I take this decision with great regret after a career of 33 years.

I am making this statement now because I will be issuing a claim against the Home Office for constructive dismissal. In the last 10 days, I have been the target of a vicious and orchestrated briefing campaign.

It has been alleged that I have briefed the media against the Home Secretary. This – along with many other claims – is completely false. The Home Secretary categorically denied any involvement in this campaign to the Cabinet Office. I regret I do not believe her. She has not made the efforts I would expect to dissociate herself from the comments.

One of my duties as Permanent Secretary was to protect the health, safety and well-being of our 35,000 people. This created tension with the Home Secretary, and I have encouraged her to change her behaviours.
