Queen and vicar to violently suppress information (8)
I believe the answer is:
victoria
'queen' is the definition.
(Queen Victoria)
'vicar to violently suppress information' is the wordplay.
'violently' indicates an anagram (letters are violently disrupted).
'suppress' indicates putting letters inside.
'information' becomes 'i' (common abbreviation for information).
'vicar'+'to'='vicarto'
'vicarto' with letters rearranged gives 'victora'.
'victora' placed around 'i' is 'VICTORIA'.
'and' is the link.
(Other definitions for victoria that I've seen before include "Queen; London station" , "State < > carriage" , "Coach may only go so far" , "It's the end of the line" , "Tree; part of hand" .)
