Request from a British politician as reported (6)
I believe the answer is:
appeal
'request' is the definition.
(appeal is a kind of request)
'from a british politician as reported' is the wordplay.
'from' becomes 'ap' (I can't justify this - if you can you should believe this answer much more).
'a british politician' becomes 'peel' (Prime Minister Robert Peel).
'as reported' shows a homophone (sound like).
'peel' is a homophone of 'peal'.
'ap'+'peal'='APPEAL'
(Other definitions for appeal that I've seen before include "Seek to have verdict overturned" , "Entreat, plead" , "Petition or attraction" , "Draw" , "Request for reconsideration" .)
