Chaperon perhaps agitated round rough oaf (5,2,6)

I believe the answer is:

guard of honour

'chaperon perhaps' is the definition.
(a guard of honour might chaperone people)

'agitated round rough oaf' is the wordplay.
'agitated' indicates an anagram.
'round'+'rough'+'oaf'='roundroughoaf'
'roundroughoaf' is an anagram of 'GUARD OF HONOUR'.

(Another definition for guard of honour that I've seen is " Ceremonial military escort".)

I've seen this clue in The Telegraph.
