Can anyone help with the id please? Seems difficult to distinguish these two species.
Thanks.

Looks like a male Besra to me. The orange iris is not good for female and juvenile. Then the throat stripe is good for Besra. The bars on tail is sometimes tricky, but width of dark to light appear to be 1:1. Length of primary projection also fits Besra.
