Supported Davey rather than Miliband? (8)
I believe the answer is:
seconded
'supported' is the definition.
(seconding is a kind of supporting)
'davey rather than miliband?' is the wordplay.
I cannot really understand how this works, but
'miliband?' could be 'ed' (politician Ed Miliband) and 'ed' is found within the answer.
The remaining letters 'second' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for seconded that I've seen before include "given support" , "Transferred temporarily to another post or area" .)
