Devious follower aiming to kidnap a king (7,2,6)

I believe the answer is:

william of orange

'king' is the definition.
(I've seen this before)

'devious follower aiming to kidnap a' is the wordplay.
'devious' is an anagram indicator.
'to kidnap' means one lot of letters goes inside another (inserted letters are kidnapped or taken).
'follower'+'aiming'='followeraiming'
'followeraiming' anagrammed gives 'willimoforange'.
'willimoforange' enclosing 'a' is 'WILLIAM OF ORANGE'.

(Another definition for william of orange that I've seen is " king".)

I've seen this clue in The Guardian.
