Emergency Workers (Obstruction) Bill

The hon. Lady mentioned St. John Ambulance. A St. John Ambulance crew attended a carnival in Chudleigh in my constituency recently, to provide first aid services. Is she aware that, if someone tried to prevent those crew members from doing that a job, it would not be offence under the provisions of the Bill? The legislation would kick in only for an ambulance capable of carrying out blue-light duties responding to a blue-light incident.
