House of Commons

Explanation:

In a system like the United Kingdom, the government is parliamentary. That means it has two houses – the House of Lords and the House of Commons.

Prime Minister is the head of the government and the leader of the House of Commons. In turn, he is governed directly by the Parliament and the monarch of the United Kingdom.

The role of the House of Commons is debating and accepting the laws, bills, and legalizations.

Prime Minister calls for elections every five years or he can be leading the House of Commons as long as Parliament gives him the support.
