Lizard giving its name to a person who often changes their opinion or style (9)

I believe the answer is:

chameleon

(Other definitions for chameleon that I've seen before include "Ha! Clone me (anag)" , "Lizard able to change its skin colour" , "One to blend in" , "Lizard whose skin changes colour" , "Self-camouflaging lizard" .)

I've seen this clue in The Times.
