Dominic Cummings has claimed evidence was being kept from Sue Gray’s investigation into drinks parties at No 10 and Whitehall because staff fear it would be seen by Boris Johnson.
The former Downing Street adviser also suggested that the fear meant that further evidence – including photos – will keep leaking after the top civil servant publishes her report.
“I know others are very worried about handing things to the Cabinet Office because they know the PM will see everything SG collects,” Mr Cummings said in his latest blog post.
He wrote: “This inevitably means that evidence, including photos, is not given to her and instead will keep leaking after her report. To stress, this is a consequence of beliefs about the PM’s integrity, not SG’s.”
Urging Conservative MPs to commit to ousting Mr Johnson from office, he added: “Other damaging stories will come out until he is gone.”
In a warning to Tory backbenchers, Mr Cummings also tweeted: “Expect the parties story to roll on after report cos photos etc will not be given to the Cabinet Office. MPs must scrap [Mr Johnson] if they want the nightmare to end.”
Officials working in No 10 have told The Independent that they have held back information from Ms Gray’s investigation into the partygate scandal due to a “culture of fear” surrounding the probe.
Three sources said they have not divulged messages and pictures on their phones after a senior member of staff told them to remove anything which could be damaging following the first party revelations.
Mr Cummings also made clear that he was not meeting Sue Gray on Monday as reported, but was submitting evidence to her investigation in writing.
The former No 10 strategist claimed that speaking to the investigating civil servant in person would give the prime minister and No 10 the chance to spin his account of events.
He wrote on his blog: “When SG (Sue Gray) asked to speak to me I emailed to the effect: if we speak the PM will invent nonsense and spin it to the media and you and I will both have problems, let’s keep everything in writing, therefore he cannot invent things I’ve supposedly said to you, there is only a written record, this makes both our lives easier.
The PM’s former adviser added: “She agreed. So I have answered questions in writing and will answer further questions in writing if she wants. But I will not speak and therefore provide the PM with more chances to lie and confuse everybody.”
Ms Gray is reportedly set to report back to the prime minister later this week before the findings are made public.
The Cabinet Office official has been tasked with investigating allegations about gatherings held in 2020 and 2021 while Covid restrictions were in place – including a “bring your own booze” event at No 10 in May 2020.
Labour’s deputy leader Angela Rayner has said the report “must be published in its entirety with all accompanying evidence”.
Mr Cummings said he would be doing a question and answer session on his blog after the report is released.
