Suspended Tory MP David Warburton faces a fresh probe from Parliament's sleaze watchdog.
The Somerset and Frome MP was already under investigation by the harassment watchdog following complaints from two women about inappropriate behaviour.
And it comes after an image emerged showing the MP for Somerset and Frome sitting next to an upturned baking tray with four lines of powder on it – alleged by the Sunday Times to be cocaine.
Today, the Parliamentary Commissioner for Standards said they had launched an investigation into possible breaches of Commons lobbying rules and the register of interests.
The watchdog's website says the investigation is into "paid advocacy", "declaration of an interest" and "Registration of an interest under Category 3 of the Guide to the Rules [Gifts, benefits and hospitality from UK sources]".
Separately, it emerged in April that Mr Warburton faced allegations that he also climbed naked into a woman’s bed and groped her breasts – after snorting cocaine.
Party bosses withdrew the whip from married David Warburton while he is under investigation by Parliament’s harassment watchdog.
When the allegations emerged in April, former music teacher Mr Warburton, who is married with two young children, denied any wrongdoing, telling the Telegraph: “I have enormous amounts of defence, but unfortunately the way that things work means that doesn’t come out first.
"I have heard nothing what-soever from the Independent Complaints and Grievance Scheme.
“I’m sorry, I can’t comment any further.”
A spokesman for the Whips Office said in April: “David Warburton has had the Conservative Party whip removed while the investigation is ongoing.”
Mr Warburton still sits as an independent MP in the Commons, where he has called for international action in “tackling the drugs trade”.
A spokesman for the Conservative Whips Office said in April: "David Warburton MP has had the Conservative Party whip removed while the investigation is ongoing."
