In Alison Weir's King and Court, it is stated that, during the trial, Lord Rochford was given a note by Cromwell regarding Anne Boleyn accusation of Henry VIII's impotence (as denounced by Lady Rochford).
I have read elsewhere that Anne Boleyn's brother would have saved his life if he had not read it aloud as this was a great embarrassment for the king.
What can you tell me about this? Is there any truth in it? What are the sources?
