"It's a disgrace that more than two years after the result of the 2016 referendum, businesses still can not plan properly for the future", Enders said in a videotaped message posted on the site of the European group.

Today's intervention by Tom Enders in which he also said "Don't listen to the Brexiteers' madness which asserts that, because we have huge plants here, we will not move and we will always be here.

Auto makers and other manufacturers, including Airbus earlier on Thursday, have warned about the toll a no-deal Brexit could impose, including higher tariffs, disruption to supply chains and threats to jobs.

Global trade secretary Liam Fox, speaking at Davos, repeated his commitment to ensuring that the UK's 40 worldwide trade deals, signed via the European Union, will continue to apply after Brexit.
He acknowledged it would be "more difficult" to ensure payment of the money in a no-deal scenario, but added: "We will continue to insist: these commitments are of a legal nature in global law and I do not imagine that the British will not respect their worldwide commitments".
