The revelation comes after weekend reports that investigators found evidence of Class A drug abuse in the corridors of power

Shocking new details of cocaine abuse in Parliament can be revealed – after Boris Johnson published the Government’s 10-year plan to tackle drugs.

The Mirror has been told how one young Tory was spotted in a popular bar with cocaine “hanging from her nostril”.

The revelation comes after weekend reports that investigators found evidence of Class A drug abuse in the corridors of power.

The Prime Minister joined a drugs raid on Merseyside today, to highlight the Government’s week-long drive on crime.

The Tory leader, who signalled middle-class drug users could be stripped of their passports, has previously bragged about snorting cocaine at university.

He told GQ magazine in 2007: “I tried it at university and I remember it vividly, and it achieved no pharmacological, psychotropical or any other effect on me whatsoever.”

He had claimed he sneezed it out, but asked if some “did creep in to your big hooter”, he admitted: “It must have done, yes, but it didn’t do much for me, I can tell you.”

Asked about weekend claims that newspaper investigators found evidence of cocaine use in Palace of Westminster toilets, a top Government minister today admitted he would be surprised if people were not taking narcotics in Parliament.

Policing Minister Kit Malthouse told Sky News: “There are obviously several thousand people who work on the estate and I would be surprised if there weren’t some lifestyle users of drugs amongst them.”

The Mirror spoke to Westminster insiders about drugs being taken on the parliamentary estate. One adviser said: “There’s a culture of work hard, play hard.

“There’s also a culture of people who don’t really live by the rules that other people live by.

“There’s lots of affairs, lots of MPs live a certain way during the week and a completely different way at the weekend – they live different lives.”

The adviser recalled one booze-fuelled evening in Parliament’s Strangers’ Bar.

She told how one Tory returned from the toilet where she had obviously been snorting cocaine.

“She was clearly out of it, I looked at her face and I could see a globule of cocaine hanging out of her nostril,” said the insider.

“I was like, ‘Is that what I think it is? Oh, yes it is’.”

Another Westminster source told how they suspected some young researchers – many of them in their first paid job and straight out of university, where they may have been exposed to narcotics for the first time – often added something “harder” to their nights out.

“You can see people getting p****d and that’s fair enough as we all work long hours,” said the source.

“But sometimes people disappear to the loos for a while and they come back and you can tell from their eyes they’re off their face.

“It’s either really brave or really stupid to do it in Parliament, given how many cops there are everywhere.”

Another source told how they had on several occasions been to the lavatories and spotted white powder which they assumed to be cocaine.

The Sunday Times reported this week that evidence of cocaine use was found in the toilets close to the Commons offices of PM Mr Johnson and Home Secretary Priti Patel.

It was also discovered in the disabled lavatory on the Shadow Cabinet corridor.

The PM’s spokesman said today: “Those reports are concerning and I know the Speaker has already talked about taking action on that.”

He added: “We do know that drugs are prevalent in society and that’s why we are focused on tackling this issue.”

Commons Speaker Sir Lindsay Hoyle has previously admitted Parliament has a “drug problem”.

Speaking in autumn 2019, when he was the senior deputy Speaker, he said: “It’s not just drink we’ve got to catch out, there is a drug problem.”

Police sniffer dogs could be deployed under plans for a crackdown.

Tory MP Charles Walker, who chairs the Administration Committee and sits on the House of Commons Commission, said:

“The House of Commons has a long history of using sniffer dogs to detect explosives.

“It may be that we now need to broaden the range of sniffer dogs … to include those which can detect drugs.”

A Parliamentary spokeswoman said: “Parliament takes the issue of substance misuse very seriously, and should drug use be identified in Parliament, appropriate action would be taken.

“Any allegation of criminal behaviour would be a matter for the Metropolitan Police.

“It is important to stress that Parliament is a public place with facilities accessed by Members, staff, contractors, press, and members of the public.”
