My azalea is looking sick. It's been rather neglected in the past - not by me. Is there any treatment for it? The last pic was June 2017.

Thank you both. Tug that's one long word there! I'll look it up.

Maybe Azalea leaf spot (Septoria azalea)? I would use Bacillus amyloliquifaciens, but I don't know what's legal in the UK.
