It's not just shoppers facing surprise costs when EU parcels arrive, but what is behind the charges?

EU official says UK threat to refuse full diplomatic status to the bloc's ambassador “not a friendly” start.

Dan Saladino finds out what the Brexit deal means for the fishing industry. Some exports and logistics companies have seen problems along the supply chain into Europe. Is this just a glitch or a long term issue?

With the UK now outside of the EU's Single Market and Customs Union, new border controls are in place and a new system for exporting goods is in place. One exporter working under this new system is David Noble whose business is based on the Scottish west coast. He describes the delays he has experienced and the extra costs he has encountered.

The company which moves most of the UK's fish across Europe is called DFDS. The head of their 'cold chain', Eddie Green explains the range of factors that disrupted fish exports, from confusion over paperwork to IT system failures.

Dan also looks at some of the longer term questions being posed by the Brexit deal, for example, how much extra fish do we now have access to?

To answer this Dan has some help from Radio 4's More or Less team who not only examined the stats behind the UK's new quota regime but also explained the calculations in a sea shanty (lyrics were by Kate Lamble, to a traditional tune, arranged by Freda D’Souza and mixed by James Beard. The singers were David Denyer, Sophie D'Souza, Will Ashcroft and on bass Moose).

The UK's exclusion zone is also on the agenda. It had been expected to be set at 12 miles but in the Brexit deal it stands at six miles from the coast. People from the industry explain why this is a big issue for them.

But what about the role of British consumers? Can our eating habits help shape the future of the post-Brexit industry? Chef Mitch Tonks explains why we need to eat a more diverse range of fish to help our fishers.

"I had no idea at all I was going to be charged any more for deliveries after Brexit… the extra costs were definitely a bit of a shock."

Ellie Huddleston, a 26-year-old Londoner, thought she would treat herself to some new work clothes in the January sales.

Having spotted a bargain, she placed an order for a coat and a number of blouses from two of her favourite clothes brands based in Europe.

But both deliveries were delayed, held up in customs checks for at least a week, she says.

She was surprised when she then received a text from courier company DPD, containing a link asking her to pay £58 in additional charges for her £180 order.

On top of that, the UPS courier for the second parcel showed up at her door several days later, asking for an extra payment of £82 for her £200 coat.

"I didn't even know when the parcels would be coming - so I sent both back without paying the extra fees and won't be ordering anything from Europe again anytime soon."
