Pleads with inspiring member of parliament to reveal bent members (3,4)
I believe the answer is:
bow legs
'bent members' is the definition.
'bow legs' can be an answer for 'members' (bow leg is a kind of member). I am unsure of the 'bent' bit.
'pleads with inspiring member of parliament' is the wordplay.
'pleads with' becomes 'begs' (begging is a kind of pleading. I am not sure about the 'with' bit.).
'inspiring' is an insertion indicator.
'member of parliament' becomes 'owl' ('parliament' is the collective noun for 'owl').
'begs' placed around 'owl' is 'BOW LEGS'.
'to reveal' acts as a link.
Can you help me to learn more?
(Another definition for bow legs that I've seen is " Members bandy".)
