Barnier says fuel crisis is direct result of Brexit
Former chief Brexit negotiator Michel Barnier has said the current Uk fuel crisis is a direct result of Britain's exit from the European Union.
Speaking at an event to promote his new book My Secret Brexit Diary, he said: "Part of the answer is linked, effectively, to the consequences of the Brexit because the UK chose to end the freedom of movement [of people].
“And there is a clear link to the truck drivers.
“In addition to the freedom of movement, the UK choosing to leave the single market – that means that the UK decided to rebuild, for the very first time, non-tariff barriers between the EU and the UK. It is a direct and mechanical consequence of Brexit.”
