Priti Patel is expected to be cleared this week of bullying senior civil servants in three separate government departments, Whitehall sources have confirmed.

The home secretary had been accused of breaching the ministerial code by mistreating staff at the Home Office, the Department for Work and Pensions (DWP) and the Department for International Trade.

She is still to face claims from her former Home Office permanent secretary, Sir Philip Rutnam, who is using whistleblowing laws to take her to an employment tribunal for constructive dismissal.

Reports of her impending clearance have prompted condemnation of the Cabinet Office inquiry process, which is conducted in secret and offers no recourse for complainants. Boris Johnson has already been criticised for compromising the process by insisting, before the inquiry had concluded, that he would continue to support Patel.

Dave Penman, the head of the FDA union, which represents senior civil servants, including Rutnam, said the cabinet inquiry process should be reviewed.

“It tells you everything that is wrong with investigations under the ministerial code that a process which is not written down, which contains no rights for those who might complain, that is determined in secret, alone by a prime minister who has already pledged his allegiance to the minister in advance, and which allows no right to transparency or challenge for anyone who complained, would then be leaked on the evening before the home secretary is due to appear before the home affairs select committee,” he said.

Informed sources said on Tuesday that Patel, the MP for Witham, is on the verge of being officially cleared. The Cabinet Office inquiry was conducted by Helen MacNamara, the propriety and ethics director general, and Sir Alex Allan, the independent adviser on ministers’ interests.

Before its findings are announced, the inquiry would have to be signed off by the cabinet secretary, Sir Mark Sedwill, and Boris Johnson.

Patel has been accused of bullying at least three officials in the Home Office. According to reports, a senior Home Office official collapsed after a fractious meeting with her. Patel is understood to have successfully asked for another senior official in the department to be moved from their job.

Rutnam subsequently wrote to all senior civil servants in the department highlighting the dangers of workplace stress, and made clear they could not be expected to do unrealistic work outside office hours.

Rutnam resigned in February and accused Patel of orchestrating a “vicious” campaign against him, of lying about her involvement in it, and of creating a climate of fear in her department.

Officials in her private office at the Department for International Development had made a “tsunami” of complaints about her behaviour, it was alleged. She was accused of ridiculing and belittling staff and exerting “heavy pressure” in emails.

There were also allegations that one member of staff at the DWP had taken an overdose after clashing with her, a charge her allies dismissed.

Labour said the inquiry into the allegations against the home secretary must be made public “as soon as possible”.



Cabinet Office minister Michael Gove was written to by his Labour opposite number Rachel Reeves, and shadow home secretary Nick Thomas-Symonds, calling for transparency. “At a time when additional powers are being assumed by the Government, the imperative that the public are completely assured of the conduct of senior ministers is even greater,” they wrote.

“As a result, we are calling on you to ensure that the findings of the inquiry are published as soon as possible. Parliament should also be updated this week about the progress of the inquiry and the timing of its completion.”

Friends of Patel have consistently argued that she has behaved properly at all times, some saying she had been the victim of sexism and snobbery from senior staff.

After Labour called for a Cabinet Office inquiry into the claims, Johnson defended Patel in the Commons, saying he would “stick with Prit”.

She is due to appear before the home affairs select committee on Wednesday morning.
