Royal 'leper' under pressure — he's not himself (4,6)

I believe the answer is:

role player

'he's not himself' is the definition.
(someone playing the role of another)

'royal leper under pressure' is the wordplay.
'under pressure' indicates anagramming the letters (letters pressurised or manipulated).
'royal'+'leper'='royalleper'
'royalleper' is an anagram of 'ROLE PLAYER'.

I've seen this clue in The Guardian.
