Britons are told to stockpile three days of water, tinned food and cash while only 13% feel ready for emergencies

The government's 'Be Ready' campaign, launched on Thursday, warns that storms, cyberattacks and Russian 'state-sponsored terrorism' could cut off power, water, phones and card payments. The official checklist calls for nine litres of drinking water per person over three days. A torch, wind-up FM radio, first-aid kit and printed documents also make the list. Some 84% of Britons say they want more guidance.

Ministers cite last winter's storms and this summer's wildfires as reasons for the push.

Lawrence Barratt of Hythe is adding tinned beans, soups and pot noodles to each weekly shop.

Officials insist the campaign does not mean a crisis is imminent.
