Universal anger about politician and judge (6)
I believe the answer is:
umpire
'judge' is the definition.
(I know this)
'universal anger about politician' is the wordplay.
'universal' becomes 'u'.
'anger' becomes 'ire' (ire is intense rage).
'about' says to put letters next to each other.
'politician' becomes 'MP' (Member of Parliament).
'ire' put after 'mp' is 'mpire'.
'u'+'mpire'='UMPIRE'
'and' is the link.
(Other definitions for umpire that I've seen before include "The ref in cricket match" , "Sports arbiter" , "Official at a cricket match" , "Person enforcing rules" , "Adjudicator in games such as cricket, tennis etc" .)
