Greg Clark insists that Britain needs a customs union with the EU after Brexit, despite the opposition of Eurosceptic ministers.
According to the Eurosceptics, Clark's intervention had been "licensed" by Downing Street. Meanwhile, the government itself denies that and calls it "absolute nonsense."
David Jones, a former Brexit minister, was quoted by The Daily Telegraph as saying: "There's no doubt Greg Clark has been licensed to say what he has said by No. 10. They ought to understand that the customs partnership is dead and finished and they should give up."
At the same time, Eurosceptic ministers say that it's time to continue with a true Brexit.
The UK is currently negotiating the Brexit deal with the EU. If at least one of the issues isn't resolved by the March 2019 Brexit talks deadline, it is likely that UK will part ways with the EU through a no-deal scenario, which may make reaching trade agreements between the two more problematic, if not impossible.
