Perhaps politician’s few words showing thorough grip (9)

Ross

I believe the answer is:

soundbite

'perhaps politician's few words' is the definition.
(a politician might deliver a soundbite)

'thorough grip' is the wordplay.
'thorough' becomes 'sound' (sound can mean reliable or thorough).
'grip' becomes 'bite' (biting is a kind of gripping).
'sound'+'bite'='SOUNDBITE'

'showing' is the link.

(Another definition for soundbite that I've seen is " Succinct extract from a speech or interview".)

I've seen this clue in The Times.
