A no-deal Brexit scenario is highly likely to result in chaos at the Port of Dover and cause huge disruption on the county's motorways, a group of MPs has warned.

A report by the Public Accounts Committee says there is a "real prospect" of "major disruption" at UK ports and warns that the Department for Transport (DfT) will not be ready in time for Britain's exit from the EU in March next year.

Preparations for avoiding delays at ports and on motorways are said to be "worryingly under-developed".

Committee members fear DfT bosses have been "complacent" in their approach to Brexit and have failed to communicate properly with businesses who will be hit the hardest.

The committee has also branded Operation Brock - which aims to prevent delays on the county's roads - as a "13-mile lorry park" on the M20.

The report goes on to highlight that tests to help introduce the £35 million Operation Brock plan smoothly "had yet to take place".

MPs have also stressed the DfT's use of non-disclosure agreements while negotiating with transport firms has hindered the spread of key information.

The report reads: "With only months to go, it is extremely worrying that we are seeing these same concerns again and again with little progress being made. Even if a deal is agreed, the Department faces a challenging workload during the proposed transition period."

Labour MP Meg Hillier, who chairs the committee, said: "We were really concerned when we spoke to the Department for Transport about readiness.

"We've got a huge issues around the roll-on roll-off ports, around lorry queues at Dover and the closure of the motorways to cope with that, we've got issues around engagement with business and also engagement with the other nations of the UK.

"If there is no deal we rip up our customs arrangements as they are and goods will have to be checked both sides of the Channel thoroughly.

"That will mean long queues.

"A delay of a minute or two at Dover can lead to several miles of tailbacks"

The UK is set to bow out of the EU on March 29 but the future is still shrouded in uncertainty as Theresa May's controversial Brexit deal hangs in the balance.

Ms Hillier added: "The government is already planning for that and planning a contraflow system and lorry parking system on the M20, and potential closure of the M26 as a lorry park.

"This could have a huge impact on the local area but also on our ability to get goods in and out of the country, particularly just-in-time deliveries.

"One of the questions we pushed them on is how they are going logistically, encourage freight and goods to go through other ports.

"We were really concerned there is still a long way to go, especially if we crash out without a deal."

The DfT has said hit back at the committee's conclusions and labelled them as not "accurate".
