Anger following English politician's rule (6)
I believe the answer is:
empire
'rule' is the definition.
(thesaurus)
'anger following english politician's' is the wordplay.
'anger' becomes 'ire' (ire is intense rage).
'following' says to put letters next to each other.
'english' becomes 'E' (abbreviation).
'politician' becomes 'mp' (Member of Parliament).
'e'+'mp'='emp'
'ire' after 'emp' is 'EMPIRE'.
(Other definitions for empire that I've seen before include "Of furniture and dress style of Napoleon I period" , "Former British rule" , "Multinational" , "Corporation" , "Several states ruled over by a single monarch" .)
