Security guards at the Bristol Royal Infirmary have been banned from wearing the Union Jack on their stab vests. It is understood that the staff had been wearing the badges for the past two months.

They are like those sold in aid of Care of Police Survivors, a charity which helps families of police officers who have died while on duty. They are becoming more common following the death of PC Keith Palmer in the Westminster attack.

The 12 members of staff, employed by the NHS, had received an e-mail telling them to no longer wear the flags on their uniforms.

ITV News approached the Trust that runs the BRI and it issued the following statement.

We were contacted recently by a member of the public who saw security officers at the Bristol Royal Infirmary wearing union jack flag patches on their uniforms. The member of the public commended the security staff on how well they dealt with a difficult incident and asked about a union jack patch that they had on their uniforms as they had not seen it before on an NHS uniform.
