The system of Salutary Neglect, which both defined the colonial system in Britain's American colonies and undermined Britain's authority in those same colonies, was influenced by what early British Prime Minister?

The benevolent period of Salutary Neglect all changed after the French and Indian War (aka Seven Years War 1755-1763) Although the French and Indian War was a victory for the British they were left with a massive war debt. To pay the war debt the British ended their policy of Salutary Neglect in the colonies.
