A Conservative MP and his wife have been accused of groping their lesbian housekeeper while trying to have a threesome with her.

The couple, known as Mr and Mrs P, also attempted to perform a sex act on the employee, an employment tribunal was told.

The Sun reports the witness claimed the pair found it funny as she fled the living room in embarrassment – and that she considered suicide afterwards.

She claims she was left with “no option” but to resign after being thrown out of the house weeks later and “threatened unreasonably with disciplinary action”.

The witness, who cannot be named for legal reasons, told the South Coast tribunal that she reluctantly accepted an invitation to have a drink in the couple’s living room in August 2012.

She said she reluctantly joined them, adding: “I sat on the sofa. Mr P came and sat down next to me, quite close so I moved up.

“Mrs P then sat on the floor between his legs. Mrs P began to French kiss Mr P. I was extremely embarrassed and hoped they’d stop.”

The woman, who had recently split with her partner, said she then felt Mrs P’s hand rub her crotch.

“I was shocked and shot into the back of the sofa. As soon as I’d done this, Mr P proceeded to place his hand on my thigh. I shot to my feet, said I’m not into this sort of thing and went into my room and barricaded my door”.

She claims she was told by Mr P weeks later that she had an hour to leave.

He gave her £300 and a letter falsely claiming they had discussed disciplinary proceedings and that a severance deal would be drawn up, she alleges.

She is claiming for sexual discrimination, unfair dismissal, wrongful dismissal and for unpaid holiday pay.

The couple deny the claims and are due to give evidence at the hearing, which continues today.
