A FORMER Tory Cabinet minister has denied allegations that he “bullied” civil servants.

Sir Alok Sharma, who was president of the Cop26 climate summit, said he had never been aware of any complaints against him.

He was alleged to have been difficult to work with, insulting staff’s work and using expletives, Bloomberg reported, citing four senior officials.

Sharma was also said to have bullied junior civil servants by calling them out of the blue to disparage their work during the pandemic, with the allegations spanning his time as business secretary and his climate change presidency from 2020 to 2022.

It was reported that concerns about Sharma's behaviour were raised with civil service bosses at least four times in 2020, though they were not official complaints.

It comes as Rishi Sunak’s deputy Dominic Raab is under investigation over eight formal complaints about his behaviour.

The Prime Minister, who pledged to uphold “integrity, professionalism and accountability” in government, is bracing for the probe led by senior lawyer Adam Tolley KC into Raab’s conduct during stints in three departments to conclude.

Raab, who is also Justice Secretary, has insisted he is not a bully.

In response to the allegations against Sharma, a Government spokesperson said: “We have no records of any complaints.”

Sharma, now a Tory backbencher, said: “I have never been made aware of any ‘informal complaints’ or otherwise from staff.

"The Cabinet Office has confirmed that there are no records of any informal or formal complaints across government about me. I refute strongly these allegations.

“I have worked with hundreds of officials as a government minister and always felt I maintained a good relationship with them, exemplified by seven of my [Business, Energy and Industrial Strategy] private office team, those officials working most closely with me, choosing to join my [Cop26] private office alongside those I had worked with in previous ministerial roles.”

The PA news agency understands that the calls made by Sharma to staff were during work hours, with the allegation regarded as weak among some in Whitehall where he is said to enjoy a good reputation.

Sharma lost his seat around the Cabinet table in Sunak's reshuffle upon entering No 10 in October.
