The end of the Brexit transition period could lead to “significant disruption” at UK borders, the boss of a haulage industry body has warned.

Richard Burnett, chief executive of the Road Haulage Association (RHA), told MPs that ministers have a “self-belief in their own rhetoric at the moment that everything will be OK”.

He said: “The devil is in the detail, and some of the fundamental things that need to change, and some of the things that need to be invested in, are simply not happening fast enough.”

Mr Burnett expressed concern about a lack of customs agents, what will happen at new customs sites and that a new border IT system has not been released.

He told the committee: “My fear at this stage is there will be significant disruption, potentially, at the year-end.”
