“‘Throughout the web of the English Criminal Law one golden thread is always to be seen, that it is the duty of the prosecution to prove the prisoner’s guilt subject to what I have already said as to the defence of insanity and subject also to any statutory exception
No matter what the charge or where the trial, the principle that the prosecution must prove the guilt of the prisoner is part of the common law of England and no attempt to whittle it down can be entertained.’
Per Viscount Sankey in Woolmington v DPP  AC 462 – emphasis added.
There cannot be an English lawyer who is unaware of this paragraph in Viscount Sankey’s judgment in Woolmington. Many non-lawyers who have chanced to read the Rumpole stories will also be as aware of, if not as attached to, it.”
