Nadine Dorries bristled over the most basic of interview questions in a bizarre appearance on BBC News this morning.
And she blamed the Prime Minister's researchers and advisers for falsehoods Boris Johnson has said in Parliament, insisting he tells the truth "to the best of his knowledge".
The Culture Secretary appeared affronted when she was asked by host Charlie Stayt when she last spoke to Boris Johnson, whom she'd been sent on TV to defend.
Asked when she'd last spoken to the Prime Minister, Ms Dorries shrugged, looked quizzically into her webcam, and replied: "Why?"
During the exchange, Stayt said he was "really confused", asking Ms Dorries if his question was a "difficult" one.
The presenter asked: "Have you spoken to the Prime Minister recently, in the last 24 hours?"
After a brief pause, a smiling Ms Dorries replied: "Why? Why are you asking me that question?"
Stayt replied: "I'd like to know."
Dorries simply said: "We've communicated."
Appearing perplexed, Stayt went on to say: "I'm really confused. Is that a difficult question? I'm just asking if you've spoken to the Prime Minister, in the last 24 hours."
Dorries repeated: "We have communicated."
Stayt went on to ask what Mr Johnson had communicated to her, but Ms Dorries declined to go into detail.
She said: "I'm not going to tell you the extent of my communications with the Prime Minister. I mean, I've answered your question. We have communicated. What is your next question?"
When Stayt asked about the PM's mood, Dorries described it as "very positive, extremely positive".
Elsewhere in her media round, she mixed up two Tory MPs with the same surname, claimed 97% of Tory MPs back the PM and blamed "remainer" enemies for plotting against him.
She admitted "there are a number of reasons actually, it's not just one", but she said: "That certainly is at play with a group."
However, out of the 15 Tory MPs who have so far publicly called on Boris Johnson to go, just seven of those had publicly backed remaining in the EU in the 2016 referendum.
One of those who has said the Prime Minister should go is David Davis, who served as Brexit Secretary, and another is strident Brexiteer Andrew Bridgen.
But Ms Dorries told Times Radio: "There are a small number of voices, whether they are people who were ardent supporters of Remain, who see this as their last opportunity to reverse Brexit."
Ms Dorries was also forced to insist Mr Johnson tells the truth as the PM came under sustained pressure over the future of his premiership.
She said Mr Johnson told the truth "to the best of his knowledge" based on what he was told by his aides.
Challenged about a claim made by Mr Johnson in the Commons about the number of people in work before and after the pandemic, Ms Dorries told BBC Breakfast: "He will have been given by advisers and researchers the fact that there were more people in work than there were at the beginning of the pandemic, not on the payroll."
She said: "So did he tell the truth when he quoted that? Yes, he told the truth as it was given to him."
"I can personally tell you that the Prime Minister, when he stands at the despatch box and makes quotes like the one you just quoted, is because the researchers and his advisers will have given him that quote, and that's... and he was truthful, to the best of his knowledge, when he made that quote," she said.
She added: "The Prime Minister does tell the truth."
Honesty was one of the key reasons former minister Nick Gibb said on Friday that he could no longer support the PM, and had submitted a letter of no confidence to Sir Graham Brady.
Writing in The Telegraph, Mr Gibb, MP for Bognor Regis and Littlehampton, said his constituents were "furious about the double standards" and he said the Prime Minister had been "inaccurate" in statements to the Commons.
He said: "The Prime Minister accepted the resignation of Allegra Stratton for joking about a Christmas party that she hadn't attended, but he won't take responsibility for those that he did attend. I am sorry to say that it is hard to see how it can be the case that the Prime Minister told the truth."
The MP said: "To restore trust, we need to change the Prime Minister."
Backbencher Aaron Bell (Newcastle-under-Lyme) also declared publicly he had submitted a letter calling for a vote of no confidence in his leader.
John Glen, a Treasury minister and Salisbury MP, said the situation with No 10 was "deeply uncomfortable, disappointing, and embarrassing".
Writing in his local newspaper The Salisbury Journal, he did not call for the Prime Minister to resign but said: "The culture in Number 10 fell short of what the country had a right to expect, and responsibility must be taken for the mistakes that were made."
The interventions brought the number of Tory MPs who have now publicly called for Mr Johnson to resign to 15.
Privately, the number is expected to be higher.
Mr Johnson also lost five No 10 aides in 24 hours on Thursday and Friday.
But Ms Dorries insisted 97% of Conservative MPs were behind the Prime Minister.
This included, she said, the Health Secretary following comments over the Prime Minister's allegation that Sir Keir Starmer failed to prosecute Jimmy Savile.
She said: "I spoke to Sajid Javid last night and he reassured me that he is 100% behind the Prime Minister.
"In fact, I think he's quite shocked at how his comments have been interpreted."
Mr Javid said Sir Keir deserved "absolute respect" for the job he did as director of public prosecutions and that it was important that the Prime Minister "clarified" his earlier accusation that Sir Keir had failed to prosecute Savile.
Earlier, Chancellor Rishi Sunak had said he would not have made the comments.
Ms Dorries said her Cabinet colleague was "entitled to his views".
Ms Dorries told BBC Radio 4's Today programme that "anybody who leads an organisation, like the Prime Minister leads the Government or Keir Starmer led the Crown Prosecution Service, when something goes wrong, you take responsibility and you apologise".
She said: "Rishi Sunak is entitled to his views and you know, he's entitled to say... make any comments that he wants to."
Ms Dorries was defending the Prime Minister as other Tory MPs are expected to consider over the weekend whether to write to the chairman of the 1922 Committee Sir Graham in an attempt to force a leadership contest.
Former minister Dr Liam Fox has said he is "waiting to see what comes out of" the full Sue Gray report into the partygate saga.
Mr Johnson was facing fresh accusations on Saturday after The Mirror reported that the Metropolitan Police had been handed a photograph of Mr Johnson holding a beer at an alleged gathering in June 2020 to mark the Prime Minister's birthday.
