I am grateful to the right hon. Gentleman for tabling his amendments. Before I turn to them, I will briefly explain why clause 2, which sets out the criteria by which premises are determined to be qualifying premises that fall within scope, is so fundamental.

I recognise that the scope of the Bill—particularly the qualifying thresholds—is an important issue to discuss. Once more, I assure Committee members that the scope of the Bill, including the thresholds, has been developed following detailed discussion with those responsible for premises and with security experts within Government. That has involved hundreds of stakeholder engagement meetings, two public consultations and the important pre-legislative scrutiny process. As a result, the Government’s firm view is that the Bill strikes an appropriate balance between protecting the public and avoiding an undue burden on premises.

Let me turn to the detail of amendments 20 and 21, which were tabled by the right hon. Member. He will be well aware that the Government have increased the qualifying threshold in the Bill from 100 to 200. As he correctly set out, clause 32 provides for the Secretary of State to be able to increase or decrease that figure and the threshold for the enhanced tier. As a result, the number of premises in scope of the Bill, and therefore required to comply, may be increased or decreased.

I assure the right hon. Gentleman and the Committee that that power is narrow, and regulations made under it will be subject to the affirmative procedure before they are made, to ensure the appropriate level of scrutiny by parliamentarians. The power is also limited in that the Secretary of State may not amend the figure to less than 100 in respect of the standard tier or to less than 500 in respect of the enhanced tier. That provides a floor, or absolute minimum number, below which the qualifying threshold cannot go.

The Government’s intention, in having the power in clause 32, is to be equipped to respond to changes in the nature or level of the threat from terrorism. We envisage that the qualifying thresholds would be reduced to either floor in only very limited circumstances, such as the nature of the threat changing significantly. The power therefore provides a necessary lever that can be used, if needed, to ensure that the legislation remains fit for purpose and continues to strike an appropriate balance between protecting the public and avoiding placing an undue burden on premises. The Government do not therefore support the amendments.

Finally, I turn to amendment 22. As I set out during oral evidence, setting a threshold inevitably raises discussion as to whether it is the right figure, and what falls on either side of the threshold will inevitably be questioned. Indeed, the Committee heard a range of views from witnesses giving evidence on Tuesday, many of whom spoke to what they believe the appropriate threshold to be. The discussion included arguments for setting it higher or lower than 200.

Ultimately, the Government have to take a view about what the most appropriate threshold is. After careful consideration of the pre-legislative scrutiny findings and consultation responses, and after taking into account the views of stakeholders and security experts, the Government have decided that 200 is the right judgment.

The amendment changing the figure to 300 would significantly impact the outcomes of the Bill, and particularly what the standard tier seeks to achieve. Furthermore, as we will discuss when we debate clause 5, the standard tier requirements have been redesigned to be relatively simple and low-cost for responsible persons to take forward. They do not require premises to make physical changes.

The Government’s firm view is therefore that 200 represents the right threshold to bring premises into the scope of the Bill. That figure strikes an appropriate balance between protecting the public and imposing a burden on premises. The Government therefore do not support the right hon. Gentleman’s amendment.
