Pool Ornament (Class: Reptilia, Order: Squamata, Suborder: Sauria)

Lizard with my finger, for scale

Having had a strimmer around the swimming pool yesterday, I went out to fish out some of the grass and discovered a live pool ornament. I managed to catch it – getting it to sit on my wrist – and relocated it to under the fennel in the kitchen garden.

Anyone know like to tell me the species?

UPDATE – this is a dragon; which specific one, still unknown. Come on, all you herpetologists out there, let’s have a name! (Both Cecil and Rodney have been suggested, although that wasn’t quite what I meant).
