No decision will be made today about Dominic Raab's future after a long-awaited report into bullying allegations against him concluded, Sky News understands.
The report was handed to Number 10 on Thursday morning and the prime minister has been "carefully considering" its findings.
However, late on Thursday afternoon, Sky News was told "no further action" will take place today.
Mr Raab, the deputy prime minister and justice secretary, has been subject to an independent investigation by senior lawyer Adam Tolley KC into multiple bullying allegations since November last year.
Mr Sunak's spokesman said he had received the findings "this morning" and under ministerial rules, it is up to the prime minister to decide what to do with the findings - and what, if any, punishment Mr Raab should receive.
The spokesman said the PM's previous expression of having "full confidence" in Mr Raab "still stands".
But "obviously he's carefully considering the findings of the report before coming to a judgment", the spokesman added.
Downing Street would not indicate when the report will be published publicly but insisted a resolution will be sought "as swiftly as possible".
Mr Tolley was tasked with determining whether Mr Raab had bullied civil servants during his time as both foreign secretary from 2019 to 2021, and then justice secretary from 2021 to 2022 under Boris Johnson's premiership.

What are the allegations against Dominic Raab?
Throughout the investigation, Mr Raab has insisted he "behaved professionally at all times" and pointed out he called the inquiry into himself when the accusations were made.
He told Sky News in February he would resign if the inquiry found he had bullied staff.
Mr Sunak now holds the cards to Mr Raab's future as the ministerial code states the prime minister is the ultimate judge of the standards expected of a minister.
The prime minister can also determine what the appropriate consequences are in the event of a breach of ministerial standards.
Mr Sunak has insisted since the inquiry began he would wait until it is concluded before he makes a decision, despite facing calls to suspend Mr Raab while the investigation took place.
Mr Tolley is understood to have spoken to dozens of witnesses, including top civil servants and Mr Johnson, following claims Mr Raab created a "culture of fear" at the Ministry of Justice, and allegations that he was "very rude and aggressive".
Colleagues were allegedly "scared" to go into his office when he was foreign secretary, former permanent secretary Lord McDonald has said.
However, a Tory MP who formerly worked as a parliamentary private secretary to Mr Raab said his ex-boss was always "courteous and professional" with his staff.
Speaking after the report was handed to Downing Street, Gareth Johnson told Sky News he can "only go by what I witnessed", but added: "Not once did I ever witness him behaving in a manner that could be described as bullying."
Mr Raab remained at work as the findings were handed over to Downing Street, responding to Crown Prosecution Service statistics on rape cases.
He issued a tweet and statement on the issue in his role as justice secretary.
The cabinet minister funded his own legal team to defend against the allegations, it emerged on Wednesday.
The declaration in the heavily delayed register of ministerial interests came despite taxpayers footing an estimated £222,000 bill for former prime minister Boris Johnson's legal fees in the partygate inquiry into whether he lied to MPs.
In the register, Mr Raab's entry notes read: "The minister has engaged lawyers at his own expense in relation to the investigation being conducted by Adam Tolley KC."
