The mother of a Thames Valley Police officer killed in the line of duty has slammed the Met Police after banning ‘memorial’ badge at Pride.

Police officers at London Pride were reportedly told not to wear the ‘Thin Blue Line’ badge commemorating officers killed in the line of duty because of concerns about its links to far-right groups in the US.

While the Thin Blue Line badge has traditionally been used to show support for law enforcement, it has become politically charged in the US, where it has been used by counter-protesters at Black Lives Matter marches.

The ban of the badge at London Pride, reported in the Mail on Sunday, was condemned by the mother of police constable Andrew Harper who was killed in the line of duty in Berkshire in 2019.

His mother, Debbie Adlam, told the newspaper that she considered the badge, which consists of a blue line stretched across a black background, to be a “universal memorial”.

“Since we lost Andrew, we have considered the Thin Blue Line image to be a universal memorial to the loss of these officers,” she said.

She added: “It concerns me that there are those who want to take (the badge) away.

“I hope that today is not the start of the end for the Thin Blue Line and all it means to us in the UK.”

On August 15, 2019, 28-year-old police constable Andrew Harper was killed near Sulhamstead, Berkshire, in the line of duty.

Harper and a fellow officer were responding to a report of a burglary, after which Harper was dragged behind a car for a mile, causing his death.

The paper reported that a Met commander ahead of Saturday’s (July 1) parade advised officers the symbol had been linked to anti-trans groups in the US.

“No ‘Thin Blue Line’ badges/patches are to be worn whilst policing this event,” the commander is reported to have said.

“These have been linked to far-right and anti-trans groups in the US and this year’s Pride is focusing very much on the trans community. This is non-negotiable and supervisors are expected to ensure this is adhered to please.”

Asked about the reported ban, a Metropolitan Police spokesman said officers can only wear insignia associated with the National Police Memorial Day Trust, Help for Heroes and the Royal British Legion charities.

“The Met’s Dress Code Policy sets out the official uniform police officers must adhere to whilst serving the public without fear or favour,” a spokesperson for the force said.

“The policy has not changed. The policy makes exception for the work of the National Police Memorial Day Trust, Help for Heroes and the Royal British Legion charities and permits officers to wear their insignia whilst on duty.”

Former home secretary Priti Patel condemned the reported ban, writing on Twitter that it was “nonsense” from “vested interest groups imposing their false narratives and ludicrous demands on our hard-working officers”.

The Mayor of London’s spokesperson said that the Thin Blue Line is “commonly accepted” as “demonstrating camaraderie” among the police.

The spokesperson added: “Subtle wearing of this imagery, eg: a Velcro patch or pin badge is not prohibited by the current MPS dress code.”
