Continuity mistake: When Churchill is delivering his first speech on May 13th, Neville Chamberlain places a handkerchief on his leg to use as a signal to his fellow MPs. During the speech you can see Chamberlain sitting a few places away from Churchill but the handkerchief is missing. Then, a short while later in the same scene, the handkerchief is back with Chamberlain's hand over it.
