Claim of the newspapermen suppressing it (7)

I believe the answer is:

profess

I'm a little stuck... Click here to teach me more about this clue!

'claim' is the definition.
(I know that profess is a more specific form of the action claim)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for profess that I've seen before include "Make open declaration of" , "Claim or declare" , "Affirm faith in (religion)" , "Affirm, acknowledge" , "State insincerely" .)

I've seen this clue in the Evening Standard.
