About this system
Voters elect the House of Commons; the Monarch formally appoints the person able to command Commons confidence as Prime Minister; Government proposes and administers policy while Parliament authorizes laws and taxes and scrutinizes ministers.
No invented arrows. A line is published only when an attached constitution or official institution explicitly supports the relationship. An institution source by itself does not justify an inferred line.
