A senior Labour MP has had the party whip suspended following reported allegations of bullying.

The PA news agency understands Christina Rees has had her party membership administratively suspended while the complaint is investigated.

The Neath MP – who was shadow Welsh secretary under Jeremy Corbyn – will now sit in the House of Commons as an independent.

I am fully co-operating with the investigation

The Guardian reported the move followed complaints by staff working for her in her South Wales constituency.

In a statement to the Guardian, Ms Rees said: “There has been a complaint made against me to the Labour Party, which is under investigation and I am therefore under an administrative suspension until the process is concluded.

“I’m not aware of the details of the complaint but I am fully co-operating with the investigation.”

A Labour Party spokeswoman said: “We do not comment on individual complaints.”
