I rise to speak to amendment 160, which stands in my name, and briefly in favour of amendments 157 and 158, also in my name. I wish to start by thanking all those who have campaigned over many years for some of the sensible changes to the Bill that we are discussing today. I also want to put on record my thanks to our fantastic police forces, including Greater Manchester Police, and also to my hon. Friends the Members for Frome and East Somerset (Anna Sabine) and for Sutton and Cheam (Luke Taylor) for their assiduous work on the Bill Committee. Liberal Democrat amendment 160 would ensure that the police cannot use live facial recognition technology when imposing conditions on public assemblies or processions under sections 12 or 14 of the Public Order Act 1986, unless a new and specific code of practice governing its use in public spaces has first been approved by both Houses. Regulations around the use of live facial recognition have been discussed many times in this House, and support for strengthening the current situation, bringing clarity and certainty to police forces, has gained support from all parts of the House, both in this Chamber and in Westminster Hall. I hope this amendment does the same today. The Liberal Democrats oppose the police’s use of facial recognition surveillance. It breaches the right to privacy and is far too often biased, particularly given its propensity to wrongly identify people of colour and women. In our manifesto last year, we committed immediately to halting the use of live facial recognition surveillance by the police and private companies. When data or technology, such as artificial intelligence, are used by the police, they must be regulated to ensure that they are unbiased. They must be used in a way that is transparent and accurate and that respects the privacy of innocent people. Policing should not intrude on this right for people who are not suspected of any crime. On the question of bias, much of the recent debate has centred around the National Physical Laboratory’s 2023 study into the equitability of facial recognition technology in law enforcement. This report is frequently cited by proponents of facial recognition, including the shadow Home Secretary, both at the Dispatch Box, when the Bill came before the House on Second Reading, and during a well-attended Westminster Hall debate last November as evidence that bias in the technology is on the decline. However, we should not overlook one of that study’s most critical findings. In live facial recognition—where a real-time camera feed is compared against a predetermined watchlist—the likelihood of false positives is not fixed. Instead, it depends heavily on the specific parameters of how that technology is deployed, particularly on the face-match threshold. That threshold, in turn, is influenced by both the size and composition of the watchlist, as well as the volume and nature of the people moving through the surveillance zone. The study recommends that, where operationally feasible, the police use a face-match threshold of 0.6 in order to reduce the risk of bias. However—and this is crucial—without clear regulation, police forces are under no obligation to adopt this or any specific standard. In other words, the presence of the technology alone does not ensure fairness. Without oversight, significant room remains for bias to persist in how facial recognition is applied. This leads to increased instances of the wrong people being stopped and searched—an area of policing that already disproportionately impacts black communities. New technologies in policing may well present good opportunities to improve public safety, and police should take advantage of them to prevent and solve crime. However, given that new technologies can raise significant concerns related to civil liberties and discrimination, we must ensure that any new powers involving them are scrutinised by both Houses. Liberal Democrat amendment 160 would ensure that the police cannot use live facial recognition technology when imposing conditions on public assemblies or processions under sections 12 or 14 of the Public Order Act 1986, unless a new and specific code of practice governing its use in public spaces has first been approved by both Houses. This will ensure democratic oversight of any changes to further legislation that may impact public privacy and civil liberties. I hope that the amendment will have support from across the House. I have just a few words to say on amendments 157 and 158, which would enable a review of antisocial behaviour powers. Antisocial behaviour, as Members have already mentioned this afternoon, blights communities, erodes trust, frays the social fabric and disproportionately affects the most vulnerable. Many colleagues have raised issues within their own communities, some of which I see in my constituency. We have off-road bikes in Heaviley, Marple, Offerton and High Lane. They are a persistent blight on my community. They intimidate people, endanger public safety and are just really annoying. But we must respond with laws that are not just tough, but fair and proportionate. That is why I urge all colleagues to support amendments 157 and 158, which would ensure that antisocial behaviour laws are reviewed before being changed, and that any new guidance is created with public input. I also welcome amendment 3, tabled by my hon. Friend the Member for Wells and Mendip Hills (Tessa Munt), which aims to ensure that the duty to report suspected child abuse covers faith groups. I encourage the hon. Member for North West Cambridgeshire (Sam Carling) to seek her out as he will find a doughty ally in his attempts to improve the Bill as it impacts on faith groups. As I said on Second Reading, there are measures in the Bill that the Liberal Democrats support. Were our amendments to be accepted, the Bill would go even further towards keeping our communities safe in a way that is proportionate and that balances the civil liberties implications of giving the police more powers. I hope that the House will support our amendments.
