The Bank of England website does not list a �100 note among their current issue banknotes. Nor does it list them amongst the notes most recently withdrawn from circulation.
Thanks for c onfirming what I thought. There is a Scottish �100 note - I think I will check if the question is correct - one of the other questions mispelt an anagram, so you never know. Thanks again.
The Scottish Banks that issue �100 notes are
The Bank Of Scotland
The Royal Bank of Scotland
&
The Clydesdale Bank.
