Panel re-assembled in division for early vote (4,8)

'early vote' is the definition.
The definition suggests a singular noun which matches the answer.

'panel re-assembled in division' is the wordplay.
I cannot quite see how this works, but
an anagram of 'panel' is 'napel' which is located in the answer.
'division' could be 'section' (synonyms) and 'section' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'for' acts as a link.
