The PM is set to face the biggest battle of his career when he speaks before Parliament on Monday afternoon, setting out further details of the “unforgivable” error by officials who failed to tell him Peter Mandelson had failed his security vetting.
Recent hours have seen Number 10 signal that the PM will accept he "inadvertently" misled MPs over the US ambassador's appointment.
Asked whether Starmer had misled parliament, the PM’s spokesperson said: "The prime minister would never knowingly mislead parliament or the public.
"He’s clear, though, that this information should have been provided to parliament. It should have been provided to him, it should have been provided to other government ministers.
"But he clearly did not have this information – that is the crucial fact – he clearly did not have this information when he previously spoke to parliament."
It comes as a written memo from Simon Case, the then cabinet secretary, penned to Starmer in November 2024, explains that if he wanted to appoint a politician like Peter Mandelson to the position of UK ambassador to the US, security vetting should take place before the appointment is formally announced.

In a Commons statement, Sir Keir will be faced with allegations he misled Parliament after telling MPs the proper process had been followed in appointing Lord Mandelson to the post of ambassador to the US, insisting he had been kept in the dark about the peer being red-flagged by security experts.
Sir Keir effectively fired the Foreign Office’s top official, Sir Olly Robbins, last week after it emerged Lord Mandelson had been given developed vetting (DV) status despite failing checks carried out by the agency responsible for assessing security clearances.
Whitehall veteran Sir Olly is expected to give his own account to MPs on Tuesday at the Foreign Affairs Committee.
The scandal has fuelled calls for Sir Keir to resign, both from opposition parties and from his critics within the Labour movement who already fear an electoral bloodbath for the party in May’s contests in English councils and the Scottish and Welsh parliaments.
The Prime Minister’s defence will be to blame officials for not telling him or the then foreign secretary David Lammy that UK Security Vetting (UKSV) had not cleared Lord Mandelson.
A statement issued by No 10 on Sunday night said that although civil servants, rather than ministers, make decisions on vetting and clearance, there was nothing in the law to prevent ministers from being told.
“There is nothing in the guidance which prevented information being shared in this scenario, in a proportionate and necessary way and subject to the appropriate procedural steps,” the statement on the Constitutional Reform and Governance Act said.
While there are “legal obligations” under data protection rules, “no law prevents civil servants – while continuing to protect such sensitive personal information – from sensibly flagging UK Security Vetting recommendations or high level risks and mitigations”.
UKSV’s privacy notice sets out that there are “limited circumstances in which relevant vetting information can be shared” if “a security risk has been identified”.
Sir Keir said he would make it “crystal clear” to MPs that he had been kept in the dark and it was “unforgivable” that the Foreign Office failed to tell him after he had offered public assurances that proper process had been followed.
The Prime Minister said: “The fact that I wasn’t told that Peter Mandelson had failed his security vetting when he was appointed is astonishing.
"The fact that I wasn’t told when I said to Parliament that due process had been followed is unforgivable, and that’s why I intend to set out in Parliament on Monday the facts behind that, so there’s full transparency in relation to it.
“But am I furious that I wasn’t told? Yes, I am. Am I furious that other ministers weren’t told? Yes, I am. I should have been told, and I wasn’t told.”
The Prime Minister will face accusations he misled Parliament – potentially a resignation matter – Tory leader Kemi Badenoch has claimed Sir Keir is “either lying or he’s incompetent”.
Asked if he would apologise to MPs on Monday, the Prime Minister said: “I’m going to set out in terms what happened.
“But I shall be making it absolutely crystal clear, as I have done a number of times, and I don’t think anybody is disputing this, that I was not told that Peter Mandelson had failed his security vetting, and I should have been told.”
He will say the information should have been provided to both him and MPs a long time ago.
Instead, the Prime Minister was only informed about the vetting issue on Tuesday evening, after it was uncovered as part of the process of gathering files related to Lord Mandelson’s appointment to comply with an order by MPs to release all relevant documents.
Allies of the Prime Minister insisted that Monday was the first opportunity he has had to set out the full facts to Parliament, despite appearing in the Commons on Wednesday for his regular question time session.
Technology Secretary Liz Kendall told the BBC: “I think one thing we’ve learned from this whole torrid episode is the need to get the facts absolutely clear and right. That’s really important.”
In a letter to the Prime Minister, Mrs Badenoch said: “As an experienced barrister you will know the importance of telling the truth, but you will also know that many people think you have been at best recklessly negligent and at worst dishonest about this whole affair.
“You have failed to answer very simple questions about what you did and what you knew. This is contemptuous of Parliament, discourteous to the House, and against the fundamental requirement set out in your own Ministerial Code.”
Lord Mandelson was sacked last year, just nine months into the Washington DC posting, after further details of his association with the paedophile financier Jeffrey Epstein emerged.
Mrs Badenoch said: “This has been a tawdry and shaming affair for you and your party, and for this country.
“Not only have you damaged our relationship with the United States and insulted the victims of the paedophile Jeffrey Epstein, but you have also undermined our national security by giving the highest diplomatic post to an individual that the security services found to be of ‘high concern’.”
