An astonishing thing for Dorries to say, even on the Dorries scale.
To state that she doesn't believe another MP is plain bizarre.
Not just that, but it's what she's claiming she doesn't believe.
it's Stanley Johnson FFS. His friends reacted to this by saying (I'm paraphrasing) 'Oh you know how Stanley is, he gropes everyone, it's harmless! You're not friends unless Stanleys felt you up!'
Literally no one else considered this didn't happen. Stanley himself didn't deny it, just says he doesn't remember, which is probably the truest thing he's said in a decade.
