Describe United Kingdom's parlimentary system of government.

Parliament is split into two houses: the House of Lords and the House of Commons. The House of Commons is the lower house and is the more powerful. The House of Lords is the upper house and although it can vote to amend proposed laws, the House of Commons can usually vote to overrule its amendments. Although the House of Lords can introduce bills, most important laws are introduced in the House of Commons - and most of those are introduced by the government, which schedules the vast majority of parliamentary time in the Commons. Parliamentary time is essential for bills to be passed into law, because they must pass through a certain number of readings before becoming a law. Prior to introducing a bill, the government may run a public consultation to solicit feedback from the public and businesses, and often may have already introduced and discussed the policy in the Queen's Speech, an election manifesto or party platform.
