The government is advising every household to keep 3 days of supplies stocked in case of power cuts, cyber attacks disrupting communications or retail, and any other emergency. I do this anyway - nearer a week/ten days of provisions actually. It’s born of the miners strikes and power cuts in the ‘70s and my military background. Those refusing because they think the government is warmongering are, forgive me, applying a strange logic. Having a few days of supplies of batteries, food and water at home isn’t going to start a war, but it might just help you in the event of disruption caused by anything. The national power supply is creaking (because of the insane, ideological and headlong rush to net Zero) and may not meet high demand over the winter = power cuts. No power, no fridge freezer, no mobile phone charging or network, no internet, no cashpoints or card readers, no tills at shops - no shopping except in smaller shops with cash. The country is under almost constant cyber attacks, which could cause similar or worse disruption, and there’s always the unforeseen. Conspiracy or no conspiracy, warmongering or not, having a small stock of supplies at home is simply a wise idea.
