Cousin Cyril mixing with cute peacekeepers? (8,7)

I believe the answer is:

security council

'peacekeepers?' is the definition.
(peacekeeping council of the UN)

'cousin cyril mixing with cute' is the wordplay.
'mixing with' indicates an anagram.
'cousin'+'cyril'='cousincyril'
'cousincyril' anagrammed with 'cute' makes 'SECURITY COUNCIL'.

(Another definition for security council that I've seen is " UN institution".)

I've seen this clue in The Telegraph.
