I wish to start by endorsing some of the comments made by the hon. Member for Bromley and Chislehurst (Sir Robert Neill) about the use of polygraphs. The Minister will know that I have been in touch with him a number of times on this particular issue, and I accept his assurances that they will be used simply for behavioural science purposes and not for legal purposes.
I wish to speak to amendments 40 and 42. As others have said, there have been a number of tragic terrorist attacks this year and there is an urgent need to protect people from further terrorist violence, but we need measures that will keep the public safe, not give the Government free rein to restrict the rights of innocent people on a never-ending basis based on little more than a hunch. We must ensure that our security services have the tools and resources that they need to do their jobs, but we must also ensure that any new powers and legislation will be necessary, effective and proportionate to the threats that we face. That is not the case when it comes to clauses 37 and 38, as they would massively expand the Home Secretary’s powers to impose terrorism prevention and investigation measures, which can include curfews and electronic tagging. These changes would essentially mean a return to control orders, as Members from all parts of the House have pointed out, and they were heavily criticised for getting the balance wrong between national security and civil liberties and were then replaced by TPIMs by the coalition Government in 2011.
There is minimal evidence that putting power in the hands of a single Minister to impose curfews and tagging will do anything to keep people safe, but it will put the rights and freedoms of innocent people at risk. These changes are opposed by the Independent Reviewer of Terrorism Legislation, Amnesty and Liberty, and the Liberal Democrats are also opposing these two clauses today. We had tabled amendments to remove them from the Bill and to keep the existing safeguards in place, and we were pleased to transfer our names to other amendments that seek to do the same.
The Liberal Democrats will continue to demand an effective, evidence-based approach to combating terrorism. Let me end by pointing out that this is the eighth counter-terrorism Bill in 10 years. If more legislation was the answer, we might have stopped these kinds of attacks by now.
