trade barrier

However, some of the global pressures may be stronger in the UK, Prof Wells said, such as fewer trade barriers against Chinese imports compared to the EU and US.

"Lifting trade barriers should boost our range of plants and products and how quickly we can get them."

Mr Baitiéh said: "Sweeping away trade barriers with the EU will remove cost, complexity and delay in food imports from the continent".

But ultimately what has been agreed so far only dismantles a fraction of the trade barriers erected post-Brexit.

Destroying all trade barriers with the EU is impossible if the Labour government keeps to its own "red lines" of not rejoining the bloc's customs union or single market.
