Nicolas Barré, in the eco editorial on Monday on Europe 1, returned to the consequences of a "no deal" in the Brexit negotiations between the United Kingdom and the European Union.

Very smart who can say how the Brexit negotiations will end: London says it is ready to consider a "no deal", but economic circles are on the rise.

The more Boris Johnson challenges Brussels, the more British but also European companies worry.

British employers, basically, agree with Emmanuel Macron: the United Kingdom "needs a trade agreement much more" than the Europeans.

The main professional federations of the Kingdom - automotive, aviation, finance, pharmacy, high tech ... - which represent 190,000 companies, are the headquarters of Boris Johnson so that he puts water in his wine and finds an agreement with the 'Europe.

Farmers are also stepping up.

Many companies are not ready to reestablish a border on January 1

They tried to prepare for it, especially in critical areas.

In the pharmacy, for example, stocks of medicines manufactured in the United Kingdom have been built up on the continent to avoid any disruption of supply: the British manufacture 2,900 references of medicines for European patients, so it is important.

In the air sector too, we have prepared: IAG, the parent company of British Airways and Iberia, has become a Spanish company with a majority of European shareholders.

Easyjet has registered most of its planes in Austria.

But in the event of a "no deal", we must still expect a few air pockets: an aircraft under the British flag will no longer be able to operate intra-European routes.

And the pilot licenses granted by London will no longer be valid in European skies.

But the main risk is customs duties

The United Kingdom would become a "third country" in the event of a "no deal", and customs duties would apply: 10% on a car for example and up to 22% on vans and trucks.

It would be a big blow for Nissan, for example, which manufactures models like the Qashqai or the Leaf across the Channel.

Nissan suggests that it would close its factory in the event of a "no deal", just like PSA, which recently bought the Vauxhall brand.

As for British consumers, they will pay dearly for a no-deal Brexit: the United Kingdom imports 87% of its cars.

Their price would therefore be immediately increased.

You see, when Boris Johnson says that London is not afraid of the "no deal", there is clearly a good deal of bluff.
