Families in United Kingdom have been urged to keep emergency supplies sufficient for at least three days amid growing concerns about security threats, cyberattacks and disruptions to essential services. The government’s Be Ready campaign encourages households to store drinking water, non-perishable food, medicines, a torch, batteries, a radio, a first-aid kit and cash in case electricity, water supplies or communications are disrupted. Families are also advised to prepare emergency plans and consider the needs of children, elderly relatives and pets. The guidance is designed to help households cope with a range of emergencies, including severe weather and potential security incidents, rather than signalling that war is imminent. Officials have encouraged people to build their emergency kits gradually and take practical steps to improve their preparedness without panicking.
