Over the past few weeks, top Tory MPs like Shaun Bailey and Allegra Stratton have resigned over the allegations of parties taking place in Downing Street.
During Nick Ferrari's Christmas special another guest on the panel. Kevin Maguire the editor of the Daily Mirror slammed the Prime Minister's lack of honesty and held his sister Rachel to account.
When asked by host Nick Ferrari what she felt when she saw the leaked picture on the front page of the Mirror, Ms Johnson said: "No I just feel incredibly sad and depressed, none of us could do anything."
A guest on the panel said: "They took us for stupid, so they sent Secretaries of State into studios including with you Nick, I heard Sajid Javid say, he didn't think there were any parties.
"So Downing Street were briefing Cabinet Ministers with false information, it was insanity, Boris Johnson should have just said, I'm going to find out about this, when he found out it happened, I've disciplined them. It should never have happened."

Ms Johnson said: "It was the Department of Education, it was the treasury, it was Shaun Bailey, it was Downing Street. I mean sorry, it was across Whitehall."
Nick Ferrari said: "A look to the Health Secretary, Sajid Javid's credit he always sounds and looks shift when he's not telling the truth, they've given him a script even he doesn't believe and he trots it out.
"But it was just a sleaze, was entirely self-inflicted by the Prime Minister to some extent so are parties, because if had put his hand up and said I will look and yes I found out we had some gatherings and we shouldn't.
"We probably wouldn't be talking about it now but it's the like and it's the cover-up, Allegra Stratton recording of her laughing that was preparing the cover=up a year ago."

Ms Johnson said: "I mean because he is my brother I've had to see him over the course of lockdown and I have to say, every time I've seen him you know if it was a rule of six he said we can only be six wherever we are.
"He spent the last week after I wrote to the Cabinet Secretary asking for an investigation into the allegations, he spent the week saying, 'nothing to see here, nothing happened."
