"In the UK, a plea of not guilty by reason of insanity at the time of a murder is a rare defence that requires proving, at the time of the act, the defendant suffered from a "defect of reason" from a "disease of the mind", preventing them from understanding the nature and quality of their actions or that those actions were illegal. This defence is based on the M'Naghten Rules and must be clearly proved by the defendant, often with expert psychiatric evidence.
