The UK is currently facing a shortage of lorry drivers resulting in food shortages in supermarkets, rationing petrol and fears the Christmas season could be plagued by further shortages.
Speaking in London at a London School of Economics event, Michael Barnier claimed there was a “clear link” between the UK’s driver shortage and ending freedom of movement.
The French politician, who served as the European Commission’s Head of Task Force for Relations with the UK from 2019 to 2021, suggested implementing non-tariff barriers between the two trade blocs had contributed to the economic crisis.
He said: “It is a direct and mechanical consequence of Brexit.”
However, he also suggested the pandemic and rising energy prices were also affecting the EU, he said: “There is “no single answer” to solve the crisis.”
Mr Barnier made the remarks on Monday whilst promoting his new book, named as My Secret Brexit Diary.
In his book he makes claims British politicians were “unprepared” for negotiations with the EU and suggested former Brexit secretary David Davis did not know the difference between the single market and the customs union.
Mr Barnier also shut down a new proposal by MEP Guy Verhofstadt which would introduce an “associate” EU citizenship for British workers in Europe who have been stripped of residency rights.
He said: “UK citizens have lost their rights because of Brexit, nothing else.”

Speaking on talkRADIO to Richard Tice, Rupert Lowe former Brexit Party MEP said last month he would choose Michel Barnier to be the next French president among his rivals Emmanuel Macron and Marine Le Pen.
He said: “I think Michel Barnier is of all of the three of those if I had to choose one of them, I’d rather do business with him.”
