Boris Johnson said it is “concerning” that the inquiry into whether he lied to MPs will rely on evidence by partygate investigator Sue Gray as she will be working for Labour.
But the Privileges Committee defended its probe, saying it is “not based on the Sue Gray report”, which last year detailed lockdown-breaking, booze-fuelled parties in Downing Street during Mr Johnson’s leadership.
The former UK prime minister and his allies have used Ms Gray’s planned move to Sir Keir Starmer’s office to try to discredit the cross-party panel’s inquiry into whether he lied to the House of Commons over lockdown breaches.
In a statement, Mr Johnson said: “It is surreal to discover that the committee proposes to rely on evidence culled and orchestrated by Sue Gray, who has just been appointed chief of staff to the leader of the Labour Party.
“This is particularly concerning given that the committee says it is proposing to rely on ‘the findings in the second permanent secretary’s report’ as ‘relevant facts which the committee will take into account’.
“I leave it to others to decide how much confidence may now be placed in her inquiry and in the reports that she produced.”
However, the committee rejected the claims, saying its inquiry is based on evidence including witnesses, WhatsApps, emails and images from a Downing Street photographer.
This is a total circus. How can the work Keir Starmer's top political adviser be used against Boris like this? This cannot possibly be a fair process.'

Arch loyalists of Rishi Sunak’s predecessor in No 10 have reacted furiously to the move by the senior civil servant who carried out the probe which played a role in Mr Johnson’s downfall.
Nadine Dorries, the former UK culture secretary, said: “Sue Gray’s evidence cannot be relied upon in any meaningful way until we know how long Sue Gray has had a personal relationship with Keir Starmer and for how long they have been discussing Sue going to work for him as his most trusted and important adviser.”
A well-placed ally of Mr Johnson said the committee’s inquiry is “beyond a farce and totally lacks credibility”, while Tory MP Mark Jenkinson called it a “total circus”.
Labour dismissed claims that Ms Gray’s move to Mr Starmer's office proved a plot to oust the former British prime minister as “ludicrous”.
No.
Sue Gray has undoubtedly broken the Civil Service code. She has unfairly damaged the reputation of all civil servants as a result. https://t.co/FPYfCsTeQy— Rt Hon Nadine Dorries MP (@NadineDorries) March 3, 2023
Shadow culture secretary Lucy Powell said Mr Johnson is using the appointment to “vindicate himself further” after he was ousted over a series of scandals.
Ms Gray will take up the role of Mr Starmer's chief of staff after following the “normal procedures”, which could include a recommended waiting period ultimately decided by Mr Sunak.
She is expected to await the decision of the Advisory Committee on Business Appointments (Acoba) before starting the role.
Parliament’s anti-corruption watchdog can advise waiting periods before civil servants take on other jobs and the UK prime minister ultimately makes the final decision.
But Downing Street made it clear that Mr Sunak cannot block her from taking a job.
Mr Johnson received one of the 126 fines issued by the Metropolitan Police while the force investigated lockdown-busting parties in Downing Street and Whitehall.
Ms Gray got the job as partygate enforcer after UK Cabinet secretary Simon Case had to step down from the investigation when he became embroiled in claims of partying during the pandemic.
Published last May, her investigation detailed how officials drank so much they were sick, sang karaoke, became involved in altercations and abused security and cleaning staff.
She criticised “failures of leadership and judgment” in No 10 and said “the senior leadership at the centre, both political and official, must bear responsibility”.
The Cabinet Office was “reviewing the circumstances” under which Ms Gray resigned on Thursday.
