Conservative MP Nadine Dorries has told of her "hurt and confusion" after David Cameron "publicly humiliated" her at Prime Minister's Questions.
Ms Dorries felt her "cheeks burn" as Mr Cameron labelled her "extremely frustrated" in a packed House of Commons last Wednesday.
The PM told her: "I know the honourable Lady is extremely frustrated", sparking laughter from MPs on all sides before Mr Cameron added: "I am just going to give up."
The incident came just moments before an "exhausted" Ms Dorries was due to unveil a controversial plan to limit advice given to pregnant women considering abortions.
She said on Sunday: "The House erupted and I was hit by a wall of noise. The Prime Minister rose to his feet. He knew how angry I was. He knew how hard I had worked on this amendment and how important it was not just to me, but to the thousands of women it would help."
Reliving her ordeal, which followed her question about Liberal Democrats in the coalition having too much influence on Government policy, she criticised the premier's "feeble" attempts to reply.
Writing in the Mail on Sunday, Ms Dorries said: "A voice inside my head screamed, 'You can't leave it at that. You can't just give up.' But he had. The chamber grew hotter and the noise more thunderous as all around me people laughed. I felt my cheeks burn.
"I sat for 10 minutes trying to read through the speech but then realised I had to get out of the chamber to compose myself. The Prime Minister had publicly humiliated me in front of the entire nation in a way that I knew would be perceived as sexist."
Mr Cameron later texted Ms Dorries apologising for the "mess". He told her: "I am genuinely, desperately sorry, it was an entirely innocent mistake. I got into a mess and couldn't get out."
A Downing Street spokeswoman declined to comment.
