I love all these remainers with there crystal ball, they can see into the future, can only see the bad, They have no factual evidence for what they are saying, when the government wisely take precautions they moan
It is perfectly possible to assess what might happen under certain conditions. This is not gazing into a crystal ball; rather it is taking the known variables and analysing what might happen.
It is a fact that if the UK leaves the EU with no deal, then a Hard Brexit will impact on the UK. Primarily regarding trade, as the UK will have no agreements in place with any other countries and there will be a hard border requiring every load to be checked.
It is a fact that the ports that are used for food and other imports from the EU (Dover plus a few smaller ports such as Harwich, along with the Eurotunnel) are currently working at full capacity and are geared to 'arrive and drive' traffic - the lorries arrive and drive on into the UK with a minimum of checks and delays.
It is a fact that if all lorries entering the UK have to have their papers and loads checked, this will greatly reduce the number of lorries that can enter the UK each day. The estimate is that 10,000 - 12,000 lorry-loads a day will be reduced to around 5,000 loads a day or less. There is not the required number of customs officers or infrastructure in place to allow any more to enter. Eurotunnel is not equipped at all to check anything other than a very small number of loads and Dover lacks the physical space to quickly check every lorry that arrives.
So now the analysis:
Assuming that only 5,000 lorries can arrive every day after 29th March, what should they contain? If the government prioritises food and medicines, then there is no capacity left for goods such as car parts and components, meaning that the factories will close and millions of people will go on short-time working or lose their jobs. If they prioritise car parts then there is no capacity for food and medicines. The government's idea that the food wholesalers and retailers should stockpile is a non-starter - there is not the warehouse capacity in the UK to store sufficient food (as they would have told Raab had he cared to ask them). Likewise, factories such as car factories would need to build huge new warehouses to hold just a few weeks worth of parts - again, this is not possible in within the timeframe and would be too expensive anyway; companies would just close and move to the EU.
5,000 food lorries a day will not satisfy the UK's food requirements, so what happens next? Do the supermarkets ration food, and on what basis? Does the government ration food, and if so, how will they register people and put in place a rationing scheme by March? Will people with special diets receive special rations? Does the market ration food - i.e only those who can afford it can buy? Does the black market ration food - only those in the know can buy food?
Whichever way you look at it, the situation after 29th March is not good if there is no Brexit deal. In the circumstances, it is prudent for each person to make up their own minds about whether or not to create their own stockpile while food is still available and affordable.
