A vote introduced by British PM for disused weapon (6-3)
I believe the answer is:
battle-axe
'disused weapon' is the definition.
'battle axe' can be an answer for 'weapon' (I've seen this before). I'm not certain of the 'disused' bit.
'a vote introduced by british pm' is the wordplay.
'vote' becomes 'x' (how votes are marked).
'introduced by' indicates putting letters inside (some letters introduce others into them).
'british' becomes 'b' (abbreviation e.g. in BBC).
'pm' becomes 'attlee' (prime minister Clement Attlee).
'a'+'x'='ax'
'b'+'attlee'='battlee'
'ax' going within 'battlee' is 'BATTLE-AXE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for battle-axe that I've seen before include "A formidable and aggressive woman - with ancient weapon?" , "Broad-bladed weapon - domineering woman" , "Large broad-bladed weapon" , "Old chopper- nagging old woman" , "Weapon - harridan" .)
