Westminster Cathedral, the UK’s largest Catholic church, is facing scrutiny following reports of drug dealing both outside and inside its historic walls, even during Mass.

Worshippers have described witnessing “brazen” drug exchanges in the pews while services were underway, raising serious concerns about safety and reverence in one of Britain’s most iconic places of worship.

The Daily Mail reported that private security staff and local residents say drug activity around the cathedral has become increasingly visible and frequent, with the area plagued by anti-social behaviour.

Their recent investigation documented multiple drug deals taking place in alcoves outside the cathedral, where vulnerable people were seen purchasing Class A substances such as cocaine, heroin and synthetic drugs for as little as £5.

Locals report that rough sleepers and drug users regularly gather on the cathedral’s steps and in nearby chapels, adding to the sense of unease.

The Diocese of Westminster told Premier Christian News: “Westminster Cathedral takes seriously any allegation of drug dealing within its premises and urges anyone who witnesses such activity to report it immediately to our security team or the police. However, our team has received no direct reports of drug dealing inside the cathedral. We are confident that, each day, more than 5,000 people visit and experience a welcoming, prayerful and safe environment.”

The Diocese said it is continuing to work closely with police and the local authority to address the problem and is encouraging the public to report illegal activity to support calls for a stronger police presence.

As concerns grow about safety at Westminster Cathedral, faith leaders and community members are calling for decisive action to protect worshippers and uphold the sanctity of this cherished Catholic site.
