British police insist security hasn't been compromised after the planner of the country's home secretary was left at a concert hall in Scotland.
London police said Thursday that it was investigating after Theresa May's planner, which contained details of appointments and phone numbers, went missing.
May had attended a concert at the venue in Glasgow on Sunday. In a statement, police said the document did not contain any classified material.
London's Evening Standard newspaper reported that the diary contained details of appointments with police chiefs, lunch meetings and gym sessions. The paper, which didn't cite a source for the information, said that the diary has since been returned to the ministry by an independent police magazine.
