I, perhaps, fix declaration (13)

I believe the answer is:

pronouncement

'declaration' is the definition.
(I know that pronouncement is a type of declaration)

'i perhaps fix' is the wordplay.
'i perhaps' becomes 'pronoun' ('I' is a pronoun).
'fix' becomes 'cement' (cementing is a kind of fixing).
'pronoun'+'cement'='PRONOUNCEMENT'

(Other definitions for pronouncement that I've seen before include "An authoritative declaration" , "ordinance" , "Official declaration" , "formal statement" , "Edict" .)

I've seen this clue in The Times.
