The BBC’s Analysis Editor Ros Atkins examines whether post-Brexit border checks were to blame for disruption at the Port of Dover at the weekend and to what extent.

Following a weekend of utter chaos at the Channel crossing, James O'Brien reminds listeners how the Tories insisted Brexit would not bring about these very issues.

Mark Simmonds, director of policy at the British Ports Association has said Brexit is responsible for delays at Dover, just hours after Liz Truss blamed the French authorities.

Port of Dover boss Doug Bannister has told LBC that it's "absolutely true" that Brexit is ultimately to blame for the extreme delays at the port of Dover because passports require extra checks.

The Government say massive delays at Dover this week are nothing to do with Brexit, while banning staff from giving interviews. / One customs agent took us inside to speak to drivers who had been waiting up to 24 hours. / Every single one of them blamed Brexit.

The Unite union says the queues of lorries outside the town of Dover are a “direct consequence” of the introduction of additional border procedures at the beginning of the year.

Lorries are continuing to face tailbacks at Dover, which have been 'sparked by new Brexit checks'.

‘It’s entirely Brexit,’ says haulier who has been caught up in 15km queues.

More ferries are to sail directly from Ireland to the European mainland in a move to circumvent the traditional trade route over mainland England and Wales.

Hauliers have claimed there will be "mayhem" at Holyhead port when the Brexit transition period ends.

‘Efficiency and effectiveness’ at risk as terror threat raised and crime becomes increasingly transnational.

The biggest operator of ferries in the Irish Sea has confirmed that there will be checks, inspections and some new infrastructure for trade, and it wants to know what the government will pay for.

Michael Gove just confirmed to me at @SeneddEAAL that the UK Government has not conducted an economic impact assessment on the effect of the Brexit deal on Holyhead Port. This did not stop him from claiming that the deal would leave Holyhead in "a stronger position than ever".

Food prices could rise between 5% and 10% if there is a disorderly Brexit, the Bank of England governor, Mark Carney, has warned.
