The Scotland Bill has its third reading stage, the final chance to debate aspects of the bill, in the House of Lords today (Tuesday 24 April).
Members will look at final changes to the bill, including national authority over speed limits and driving vehicle regulations in Scotland.
Lords will also discuss the role of the Lord Advocate or the Advocate General for Scotland during criminal proceedings.
What is third reading?
Third reading is the final chance for the Lords to debate and change the contents of the bill.
The day before third reading starts, amendments are published in a marshalled list in which all the amendments are placed in order. Amendments on related subjects are grouped together and a list is published on the day.
Amendments at third reading in the Lords are often used to clarify specific parts of the bill and to allow the government to make good any promises of changes to the bill made at earlier stages.
Next stage: Consideration of amendments/ping pong
Once the bill has completed its passage through the second chamber the bill will return to the Commons where they will consider any amendments made.
Both Houses need to agree to the exact wording of the bill and the bill may 'ping pong' between both houses until this happens.
When the exact wording of the bill has been agreed by both Houses the bill is ready for royal assent. Once a bill receives royal assent it becomes an Act of Parliament (proposals in the bill become law).
