At the start of the debate, the motion on the first estimate selected for debate will be moved formally. One of the MPs who submitted the bid for the debate to the Backbench Business Committee will make the opening speech. The minister will usually speak at the end of the debate and the MP who moved the motion might get time to speak again briefly after the minister.
Once the debate on the first estimate has finished, the same pattern is followed for the debate on the second estimate.
Decisions on all the estimates—including the ones that have been selected for debate — take place at the moment of interruption (the point at which the main business must usually end).
In the case of the supplementary estimates, when there is one day of debate, decisions take place at the moment of interruption on that day. In the case of the main estimates, when there are two days of debate, decisions take place at the moment of interruption on the second day.
At the end of an estimates day—or if there are two estimates days, at the end of the second day— the Speaker will put separate questions on the estimates which the House has debated, along with any selected amendments to them.
Once these estimates have been agreed, the Speaker will then put the rest of the outstanding estimates for approval formally, even though the House has not debated these. This is known as a roll-up motion. You can’t vote for or against individual estimates in the roll-up motion—only for or against the whole package.
