Biggest part of Last Leg is starting with introduction from Adam Hills nailing MPs? (11)
I believe the answer is:
legislators
'introduction from adam hills nailing mps?' is the definition.
I can't tell whether this defines the answer.
'biggest part of last leg is starting' is the wordplay.
'biggest' becomes 'or' (I can't justify this - if you can you should give a lot more credence to this answer).
'part' means one lot of letters goes inside another (the inserted letters split open or part the word).
'of' indicates an anagram (the answer comes from or 'of' the letters).
'starting' says to put letters next to each other.
'last' with letters rearranged gives 'lats'.
'or' going within 'lats' is 'lators'.
'leg'+'is'='legis'
'lators' put after 'legis' is 'LEGISLATORS'.
'with' is the link.
Can you help me to learn more?
