Reportedly vote against book belonging to us reaching someone close (9)
I believe the answer is:
neighbour
'someone close' is the definition.
(I've seen this before)
'reportedly vote against book belonging to us' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'vote against' becomes 'nay' (as in aye or nay).
'book' becomes 'b' (abbreviation for book).
'belonging to us' becomes 'our' (us, you and me).
'nay' sounds like 'neigh'.
'neigh'+'b'+'our'='NEIGHBOUR'
'reaching' is the link.
(Other definitions for neighbour that I've seen before include "One living next door" , "One lives nearby" , "Nearby resident" , "possibly providing part of watch?" , "Huge Robin (anag.)" .)
