Some points from Rag's story, (originally Dave's and mine) from the original source.
The research quoted only consideed Tory MPs.
The accusation against 4 Labour MPs were made elsewhere.

"It includes claims of sexual misconduct against 37 male and female politicians, including sexual harassment allegations and reported extramarital affairs. More than 25 are alleged to have been “inappropriate with female researchers”."

Examples given,
"A prominent female MP is accused of having extramarital sex with young male researchers. At least two MPs are accused of getting their mistresses pregnant, with one allegedly paying for her to have an abortion. Other MPs have reportedly had sex in their private offices in Westminster while two Conservative politicians are accused of using the services of prostitutes.
The list also alleges that a video is circulating of one Tory backbencher engaged in an extreme sex act with three men."

No suggestion of anything no-consensual.
