June Keaton (Tuppence Middleton) is a character who appears in "Spooks: The Greater Good" and who is an MI5 Officer. June is seen only in the film and not the Television series and so either joined MI5 sometime after the series ended or worked in some other area of the organisation.
We first see her at the beginning of the film where she is part of the prisoner transport for Adem Qasim. When Harry Pearce is forced to let Adem free, June is one of the agents who chases after him and attempts to re capture him.
