Britain's Road Haulage Association says it is " very concerned" French customs action is leaving lorry drivers vulnerable to migrant attacks.

Members have reported chaos at French Channel ports and Eurotunnel as customs officials are said to be working to rule in a dispute concerning working conditions and fears of a no-deal Brexit.

"One haulier told us they abandoned a number of planned Channel crossings last week after migrants tried to break into a lorry whilst the driver was held in a queue for 12 hours outside Dunkirk," said an RHA statement.

RHA chief executive, Richard Burnett added drivers "have a right to do their job safely and shouldn't be left vulnerable to attacks from migrants and people smugglers.

"Yet again we're hearing horrifying stories of truckers running a gauntlet of people trying to break into their lorries. It's completely unacceptable. The French authorities need to do more to protect UK-bound lorries."
