In fix, getting nothing after foolishly trusting flipping politicians (6,4)
I believe the answer is:
fianna fail
'politicians' is the definition.
(Irish political party)
'in fix getting nothing after foolishly trusting flipping' is the wordplay.
I cannot really understand how this works, but
'nothing' could be 'fa' (slang term - sweet Fanny Adams) and 'fa' is found within the answer.
'fix' could be 'nail' (I've seen this before) and 'nail' is located in the remaining letters.
This may be the basis of the clue (or it may be nonsense).
(Another definition for fianna fail that I've seen is " party in Ireland".)
