Police believe device was deliberately planted near frontbench to disrupt proceedings, prompting heightened security in parliament

Police have arrested two men in connection with a mobile phone hidden in the House of Commons that was reportedly planted there to play sex noises during prime minister’s questions.

The phone was found near the frontbench during a routine sweep of the chamber. It is believed to have been intended to interrupt the keynote weekly showdown between Keir Starmer and Kemi Badenoch in September.

The police believe the phone was deliberately placed to cause disruption. A Metropolitan police spokesperson said: “At 10.25 on Wednesday 3 September a mobile phone was found during a routine search of the House of Commons chamber by Met officers.

“Enquiries led officers to believe that the phone was purposely placed in a location with the aim of causing disruption to business in the house.
