The Bank of England has never issued a One Million Pound note for general circulation.
Since the various note issuing banks of Scotland and Northern Ireland are backed by the Bank of England, the Bank of England produces One Million and One Hundred Million Pound notes for the use of the note issuing banks, so that they can hold equivalent values of Bank of England notes. They are strictly for internal use and have probably never been seen outside of the vault.
The Bank of England first issued a regular Fifty Pound note in around 1725. The Bank of England issued the modern Fifty Pound note in 1981.
