Agrees to allow use of chavs in action (10)

I believe the answer is:

vouchsafes

'agrees to allow' is the definition.

'use of chavs in action' is the wordplay.
'in action' is an anagram indicator (I've seen this in other clues).
'use'+'of'+'chavs'='useofchavs'
'useofchavs' is an anagram of 'VOUCHSAFES'.

(Another definition for vouchsafes that I've seen is " Bestows".)

I've seen this clue in The Telegraph.
