Lyric discussion by Beery 

Regarding the lyric "She spills with compassion": in the Middle Ages spill referred to much more devastating things than it does today. Spillan, the Old English ancestor of Modern English spill, meant such things as "to destroy, mutilate, kill." I think perhaps Elvis Costello was (consciously or subconsciously) tuning in to that older meaning when he wrote this line.

mmm, I think you may be over-analysing this. Thatcher was reknowned for her furrowed eyebrows and tilted head as she leaned forward in a low whisper to say something 'compassionate' from the 'heart' (although there's no evidence that she possessed one, there is plenty of evidence to suggest she may have been possessed). She was truly a wolf in sheeps clothing
