Constable Jones is a minor character in Mary Poppins.
Constable Jones is a policeman with Scotland Yard and is often seen patrolling the neighborhood where the Banks family resides. He appears to be a kind and dutiful man but shows a dislike for how George Banks treats his family and servants.
Constable Jones appears early in the film, as a spectator of Bert's one-man band. When Bert solicits donations from the crowd for his performance, Constable Jones is specifically told that there is no charge.
That evening, he arrives at the Banks' home, just as George is calling the police to report his children missing. Constable Jones reveals that he found the children, and urges George not to be too hard on them. When they excuse themselves by stating that they had lost control of their kite, Constable Jones agrees and begins a conversation. However, George cuts him off, thanking him for returning the children, and offers him "a plate of something" from the kitchen. He leaves, muttering about George's attitude. For most of the film, he appears only as an extra in certain scenes.
Near the end of the film, Constable Jones is summoned to the Banks' home again. George has been missing since the night before, and his family fears he may have become suicidal after losing his job. While Constable Jones is on the phone with an Inspector giving George's description, George abruptly appears from the cellar, having spent the night repairing his children's broken kite. Constable Jones, amazed by George's sudden change in behavior, recounts George's arrival to the Inspector and watches them go off kite flying.
