M20 backlog caused by French authorities testing post-Brexit checks at the Eurotunnel
Queues of trucks stretching for five miles unexpectedly built up in Kent on Tuesday after the French started a trial of post-Brexit checks in Calais.
Lorries on their way across the English channel were forced to stop in long lines up to junction 11 on the M20 as they tried to approach the Eurotunnel entrance just outside Folkestone.
