The mother of a woman murdered by a repeat domestic abuser weeks after police were meant to warn her will ask MSPs to back calls for an urgent Fatal Accident Inquiry.
Caroline Lyon will visit the Scottish Parliament on Thursday, the second anniversary of the murder of her daughter, Louise Aitchison, to ask politicians to support a swift inquiry to establish how her daughter was failed by Police Scotland and ensure lessons are learned.
The force has apologised to her and admitted 18 separate errors meant a formal warning that her daughter's new boyfriend had a history of domestic abuse was never delivered before she was killed.
