Why did England come to be called a constitutional parliamentary monarchy?

England began to be called a constitutional parliamentary monarchy because, in the course of various reforms associated in many respects with the revolution in England, in addition to monarchical power, a parliament and a prime minister also appeared, and a constitution was written. As a result, the power of the king in the country became limited by the parliament, which served as the legislative body of state power. It was also a new knowledge that the cabinet of ministers began to be formed only by the parliament itself, and all acts and decrees of the king began to acquire force only after their approval by the legislature.
