Demanding, revolting and annoying (9)
I believe the answer is:
maddening
'annoying' is the definition.
(synonyms)
'demanding revolting' is the wordplay.
'revolting' is an anagram indicator.
'demanding' with letters rearranged gives 'MADDENING'.
'and' is the link.
(Other definitions for maddening that I've seen before include "Infuriating by being demanding" , "vexatious" , "Aggravating - furious" .)
