What is the report stage of a bill?
The report stage gives MPs an opportunity, on the floor of the House, to consider any further amendments (proposals for change) to a bill which has been examined in a public bill committee or on the floor of the House. There is no set time period between the end of committee stage and the start of the report stage.
What happens at report stage?
All MPs may speak and vote. For lengthy or complex bills, the debates may be spread over several days. All MPs can suggest amendments to the bill or new clauses (parts) that they think should be added.
What happens after report stage?
Report stage is usually followed immediately by debate on the bill's third reading.
What happens at third reading?
Debate on the bill is usually short, and limited to what is actually in the bill, rather than, as at second reading, what might have been included.
Amendments (proposals for change) cannot be made to a bill at a third reading in the Commons. At the end of the debate, the House decides (votes on) whether to approve the third reading of the bill.
What happens after third reading?
If the bill started in the Commons it goes to the House of Lords for its first reading.
If the bill started in the Lords it returns to the House of Lords for consideration of any amendments the Commons has made.
