Labour retains original manifesto, initially creating disquiet (7)
I believe the answer is:
turmoil
'disquiet' is the definition.
(I've seen this before)
'labour retains original manifesto initially' is the wordplay.
I cannot quite understand how this works, but
'labour' could be 'moil' (synonyms) and 'moil' is found in the answer.
'original' could be 'ur' and 'ur' is found within the answer.
A single letter 't' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'creating' acts as a link.
Can you help me to learn more?
(Other definitions for turmoil that I've seen before include "upset" , "Disquiet" , "Hubbub" , "Wild disorder" , "Chaos" .)
