There are no english £100 notes. However, Alan Turing would make an excellent candidate for any new note design, not just a one off special one. It would be nice to have him alongside darwin on the money, his ideas are arguably as profound, but much less generally appreciated. Hopefully some of the events for his centenary will go some way towards teaching people that he did a lot more than just the enigma machine.

Shame they couldn't hold off the new batch of £5 notes they're currently putting into circulation until next year.
