Food shortages, shortages of medicines, no sandwiches, no music etc etc. Utter poppycock
Food shortages - all the major food retailers have warned of shortages if the supply of fresh food from the continent is interrupted, and most are stockpiling foodstuffs to try and mitigate it. Do you claim they are all wrong? Where's your evidence?
Medicine shortage - if there won't be a shortage why has the Brexit-supporting health secretary told us he is "the largest orderer of fridges in the world" and is stock-piling them. Do you claim he is wrong? Where's your evidence?
