Yes it is more complicated than simply blaming Brexit for everything, but which of the promised gains pledged by Boris and co have actually been delivered to offset the obvious negative impacts ?
Brexit is directly responsible for the Police losing access to ECRIS and SIS2, Brexit is directly responsible for the queues at European airports, Brexit lost a part of our trade with the EU, by far our largest trading partner, and is the cause of the additional "red tape" that is now encountered when trading with the EU.
Just to be clear, although I voted remain, after the result I posted on here that I thought it was a mistake, that the promises would not materialise, but that we had to accept it and make the best of it. It is that last bit that has clearly not been achieved, and I don't know if anybody has any idea as to how to do so.
