After a new Bill has been discussed in the Committee stage, it is reported to the whole House, including any ammendments made in committee. It is possible to move further ammendments at this stage, and the proposer of the Bill may move ammendments to give effect to undertakens given in committee. With Government Bills, it is not unusual for the Opposition to attempt to force further ammendments, sometimes with a view to slow the passage of the Bill. The Speaker is empowered to decide which ammendments are open to debate, and which are not. It is therefore unusual for Opposition ammendments to be accepted at this stage.

After report -- sometimes immediately after -- the Bill receives its Third reading.
