GabriellaG54, forty-four percent of the UK's fresh, chilled and frozen food comes through the Channel ports from the EU. As has been stated and acknowledged even in government documents in recent days, that should Britain leave the European Union without a customs agreement then severe disruption will occur through those posts. That is what faces everyone in this country while a "no deal" prospect remains on the table.
GabriellaG54, your response to that situation was made clear in your post @ 21:59 today (24/01/18) being nothing but Brexiteer bluster containing no reasonable argument.
Within that, you still have no words for the many thousands who face the most severe prospect of the losing their employment because of "Brexiteer bluster, lies and financial fraud during the referendum campaign.
As the CEO of Airbus started today " Britain on its own is too small to encourage multi-national companies to locate their operations here. The world is made up of large nations and trading blocks that hold sway in location for large scale manufacturing, the higher service industries and many professions.
The above is the truth of the Brexit situation. However, those supporting Brexit without a customs agreement or any agreement whatsoever still do not believe what they witness in front of their own eyes, preferring instead to wave the Union Jack and sing "Rule Britania" with many on this forum carrying out that from the privilege of their retired armchairs with nothing to lose, or so they hope.
