Record second thoughts about recent requirement for country reps (2,6)

I believe the answer is:

cd plates

'requirement for country reps' is the definition.
(corps diplomatique vehicle plates for diplomats)

'record second thoughts about recent' is the wordplay.
'record' becomes 'cd' (I've seen this in other clues).
'second thoughts' becomes 'ps' (as in a PS in a letter).
'about' means one lot of letters goes inside another.
'recent' becomes 'late' (similar in meaning).
'ps' going around 'late' is 'plates'.
'cd'+'plates'='CD PLATES'

I've seen this clue in The Guardian.
