In Parker231's link, Matt Hancock says that the UK is making plans for stockpiling drugs and medicines and that the tender has been issued for warehousing.
Which is all very well, except that the devil is in the detail.
Nissan, Toyota, BMW and every JIT manufacturer in the UK have also planned to stockpile components; so they need warehouses and have probably already signed contracts for them.
Sainsburys, Tesco, Morrisons and every food wholesaler and producer also need warehouses, as they have been planning for disruptions in the food supply chain. They will of course also have secured their warehouses already - particularly any cold stores that are vital for perishable goods.
Which means that what few warehouses that were available will have been spoken for long ago. Given that there is not much empty warehouse capacity available anyway, and very little in the way of cold storage for perishable medicines, the government seems to have completely missed the seriousness of the situation.
Finally, stockpiling is only a temporary solution. Six-weeks worth of food or drugs only alleviates the problem for six weeks. Unless there is a lasting solution which means that supplies return to normal fairly quickly, all that will happen is that the UK runs out of medicine and food in mid-May instead of at the end of March.
