I think we will see a fair nuber of withdrawals and going in to administration all blaming the “brexit” banner. Which ones are genuine remains to be seen, but i dont think we will ever get behind the truth of the matter. When i see the success of JCB with or without brexit it does make one wonder about all the brexit blame game.
Most company failures are multifactorial - most often the “final straw” will not necessarily be related to the underlying reason for the failure of the business.
However, I bet that Brexit will be the final straw for a good many struggling businesses.
