All Tories, after reshuffle, embracing good politician (10)
I believe the answer is:
legislator
'politician' is the definition.
(legislator is a kind of politician)
'all tories after reshuffle embracing good' is the wordplay.
'after' says to put letters next to each other.
'reshuffle' indicates anagramming the letters.
'embracing' indicates putting letters inside.
'good' becomes 'g' (abbreviation).
'all'+'tories'='alltories'
'alltories' is an anagram of 'leislator'.
'leislator' going around 'g' is 'LEGISLATOR'.
(Other definitions for legislator that I've seen before include "One in Westminster perhaps" , "Lawgiver" , "lawman" , "Parliamentarian" , "Lawmaker" .)
