Gave up after an hour with the SW untouched and looked up the answers . Despite the various hints below I can't see the Spoonerism (nothing new there) -can someone please break it down into minute pieces without saying what the answer is, please?
I didn't know Elizabeth I was what the answer is for 26a and don't recall having heard of the sorcerer at 21a .
Having finished yesterday's FT in about 30 mins , I have to say this was much harder .
