Answer & Explanation: John Locke was a British philosopher, Oxford academic and medical researcher and concerning his ideas on government, he was of the opinion that a legitimate government is based on the idea of separation of powers.
The theory of separation of powers is a model of governance that is common in democratic states which features the division of the sovereign power into at least three (3) organs. This can get up to six (6) organs sometimes and are in place in order to forestall tyranny.
It achieves this by preventing the acquisition of a monopoly of power by an oligarchy or monarch.
Locke divided his into the legislative power, which he describes as supreme; the executive power that is charged with enforcing the law; and lastly, the federative power which consists of the right to act internationally according to the law of nature.
