Whose theories found their practical reflection in the establishment of a parliamentary monarchy in England?

Two theories of T. Hobbes and J. Locke received wide support. Hobbes argued that since the state is formed voluntarily by the will of the people, then all power should belong to the people. John Locke, in turn, proposed the division of power into separate branches. In such a division, the legislative power is concentrated in the hands of deputies elected by the people (in parliament), the executive power is headed by the monarch, and the Supreme Court is headed by the judiciary.
