Labour peer Lord Hain has again used parliamentary privilege to reveal allegations of “hundreds of grievances cases” raised against Sir Philip Green.

Speaking in the House of Lords, Hain revealed further details on the allegations of sexual harassment and verbal abuse made against Green, which he initially revealed last year by reading the account of one alleged victim.

Hain claimed the victim “plead[ed]” him to name Green under parliamentary privilege and said “hundreds of grievance cases were raised with HR” regarding Green’s behaviour, which ranged from slapping employee’s bottoms to grabbing their thighs and breasts.

The same person told Hain that Green shouted at staff who objected to his inappropriate behaviour to “go to psychologists”.

Hain also claimed the alleged victim said staff that took their complaints to an employment tribunal ended up settling after signing non-disclosure agreements and “the company lawyer who interviewed” the victim went on to lie to them.

“Some were worn down by the spiraling legal costs costing them a fortune. He broke some in the end. It was horrible. He is still doing the exact same thing. It is rife, it happened all the time,” Hain said he was told.

Hain initially used parliamentary privilege to name Green as the subject of The Daily Telegraph’s investigation of a businessman at the centre of multiple sexual harassment and bullying allegations in October after the newspaper was served an injunction preventing it from publishing Green’s identity.

Hain said his motive to name Green “was to stand up for ordinary employees against a very powerful and wealthy boss who, as described, seemed to think he was above the rules of decent, respectful behaviour”.

Green has previously “categorically and wholly” denied the claims levelled against him by Lord Hain.

He said in response to Lord Hain’s latest allegations: “How sad somebody who already has proven they’re prepared to abuse the system wants to continue to behave in this manner.”
