Declare Vera wrong (4)

I believe the answer is:

aver

'declare' is the definition.
(averring is a kind of declaring)

'vera wrong' is the wordplay.
'wrong' indicates an anagram.
'vera' anagrammed gives 'AVER'.

(Other definitions for aver that I've seen before include "Declare or insist" , "Assert, state as true" , "protest" , "Maintain - state" , "State firmly and positively" .)

I've seen this clue in the Evening Standard.
