Generous politicians? (8)
I believe the answer is:
liberals
'generous politicians?' is the definition.
'liberals' can be an answer for 'politicians?' (liberal is a type of politician). I'm not sure about the 'generous' bit.
'generous politicians?' is the wordplay.
'generous' becomes 'liberal' (similar in meaning).
'politicians?' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'liberal'+'s'='LIBERALS'
Can you help me to learn more?
(Other definitions for liberals that I've seen before include "Members of a British political party" , "They favour progress and reform" .)
