Before I start on the very last part of this quite brilliant puzzle, can I get some help on these two ...
Man's given name of Blue Arum (4)
I have the middle two letters and, after filling in the perimeter, I have it beginning with U which doesn't seem to produce any word or name? If it began with O then it could produce a man's (Middle Eastern) name - where have I gone wrong?
Cargo fiddle supported by European iniquity (5)
I have a word meaning "iniquity" but I just can't see how it's parsed?
