Aside from the play, from the historical facts, Oswald Mosley lived until 1980 and died naturally. During World War II, Churchill covered the sky with his hands in England. It was not difficult to kill Oswald, who was pro-Nazi. However, he did not do so. He put Oswald in prison and called it imprisonment, which was actually a protection. There are two reasons: one is Oswald's meritorious service in checking and balancing communism; the other is to reserve a way for the British Empire. Once Britain is defeated in World War II, Oswald can come forward to organize a pro-German and pro-Nazi government to reduce the loss of the British defeat. The royal family will not be sent to the guillotine.
The screenwriter also respects these historical facts and considerations. Churchill (or the British royal family) does not want Oswald Mosley to die, so in the play, Churchill and Tommy test each other in the office, which seems to be an alliance, but it is Churchill. Knowing Tommy's hole cards, Churchill sent someone to kill the killer and protect Oswald Mosley, but to save Tommy's life to counter Oswald.
So Finn’s lax mouth does not affect the ending, and Tommy himself first revealed his true intentions.
