The clause by clause consideration of a parliamentary bill takes place at its committee stage.
In the Commons this usually takes place in a standing committee, outside the Chamber, but occasionally a bill will be considered in a committee of the Whole House in the main chamber.
This means the bill is discussed in detail on the floor of the House by all MPs.
Any bill can be committed to a Committee of the Whole House but the procedure is normally reserved for finance bills and other important, controversial legislation.
The Chairman of Ways and Means presides over these Committees and the mace is placed on a bracket underneath the Table.
