Spotted at perimeter of Regents Park Zoo on Buddleia. Looks like this ragged specimen got fed up with confinement and made a bid for freedom. Any Ideas?

I think this is Siproeta stelenes (the malachite). It's in poor condition and I considered Philaethria dido (the Dido longwing) but what can be seen of the wing shape and forewing pattern doesn't look right.

Probably escaped from nearby London Zoos butterfly house

I feel for the poor thing in this stormy weather.

Yes, I agree with Guy, it's a Malachite.
The colours are a bit off due to the zoom and exposure, but the venation in the largest yellow patch on the hindwing matches exactly.
