My right hon. Friend makes some very pertinent observations. The emergency services work together to respond to suspected terrorist attacks, through the joint emergency services interoperability principles—JESIP—which are designed to improve joint working among all the emergency services. The JESIP doctrine complements the single-service and specialist multi-agency guidance. When a particular attack has an online element, which he refers to, we will enact our crisis response protocol, an element of practice that has been designed to deal with situations of that character.
