Bobby Turnbull, who lost three family members in a shooting in Horde, County Durham, has had a response to his campaign for tighter gun control.
Bobby's mother, sister and aunt were shot dead last year, and he has been to London to lobby politicians.
The Home Office has released guidance that says people with a history of domestic violence should notbe allowed to possess a firearm or shotgun. The publication also says every incident shouldprompt a police review.
The new guidance will form part of the Firearms Guide. Police will use it when they are deciding whether to grant a certificate.
