What is the legislative process?
The legislative process is the series of stages a bill must pass through in Parliament before it becomes law
Most legislation is introduced by the government, although some bills are proposed by backbench MPs or the House of Lords

Consideration of amendments (‘ping-pong’)
If the second House amends the bill, it returns to the first House for consideration
This process is known as parliamentary ping-pong
The bill may pass back and forth several times until agreement is reached
If agreement cannot be reached, the government may use the Parliament Acts to force the bill through the House of Lords
Royal assent
Once both Houses agree on the final text, the bill is sent for royal assent
Royal assent is a formality and has not been refused since 1708
Once granted, the bill becomes an Act of Parliament
