First and second reading
A bill is formally introduced, then MPs debate its principle. If it fails the second reading vote it goes no further.
Committee and report
A smaller group examines the bill line by line and proposes amendments. The whole House then reviews those changes before a final Commons vote.
Lords and Royal Assent
The Lords repeat the process and can send amendments back. Once both Houses agree, Royal Assent makes the bill an Act — a formality since 1708.
