I share some of the concerns expressed by Sarah Olney. Last week I spoke to businesses and officials working on Ukraine’s critical national infrastructure, who are on the frontline of Russian cyber-attacks. They told me that, since the invasion, there have been cyber-attacks on virtually every aspect of Ukrainian life, and highlighted the scope of the damage they have done to civilian and military operations. Can my right hon. Friend say a little more about how we are learning the lessons from this conflict and what we are doing to protect our own national infrastructure from Russian cyber-attacks?
