WATCH: Boris Johnson gets a shock from prisoner's Kinder surprise drug plug
Boris Johnson saw more than he bargained for during a visit to Leeds as part of his tour to promote his new anti-crime spending splurge.
You've got to feel for the poor prison guard at HMP Leeds who was given the unenviable task of showing the Prime Minister X-ray images of an inmate's rectum during a media tour on Tuesday.
Mr Johnson was left baffled after he saw the casing for the popular kids treat lodged in the digestive tract of a lag who had hoped the ruse would allow him to smuggle contraband into the jail.
Despite the tactic being common knowledge among prison staff and even the most casual viewers of Brit Cops, the PM created an awkward moment for Justice Secretary Robert Buckland and guards as he tried to figure out the mechanism for how the Kinder surprise ended up lodged in situ.
"A Kinder egg?", he asked. "Is that inside the? He's ingested it?"
Despite several anguished glimpses towards the press pack, Mr Buckland was spared the task of explaining the mechanics of the smuggling trick to his boss after the prison guard cheerily informed Mr Johnson the drugs had been "plugged" rather than swallowed.
Recoiling from the screen, the Prime Minister said: "He's plugged it? You are joking."
Mr Johnson's biology lesson followed a fresh pledge from minister to spend £2.5bn to create 10,000 new prison places and purchase dozens of the new high tech imaging machines to reduce the amount of drugs and contraband being smuggled into prison.
Speaking during the visit Mr Johnson said the funds would help stop prisons being "factories to turn bad people worse".
He added: "What we are going to do is put £100 million into scans and checks of all kinds to protect the staff and to stop the prisoners bringing in, to put it bluntly, in their alimentary systems, drugs and mobile phones, which greatly degrade life in prisons."
Conservative Campaign Headquarters have spent an eye-watering £25,000 on Facebook ads targeting people who are afraid of rising crime in their neighbourhoods.
