Do justice to the conservatives (5)
I believe the answer is:
right
This could be a double definition.
'do justice' is the first definition.
'right' can be an answer for 'justice' (right is a kind of justice). I'm not sure about the 'do' bit.
'the conservatives' is the second definition.
(right-wing people)
'to' acts as a link.
Can you help me to learn more?
(Other definitions for right that I've seen before include "Correct; proper" , "Correct; appropriate" , "Correct - claim allowed" , "Girth (anag)" , "''The customer is always .....''" .)
