The existing arrangements expire at the end of the month, with the UK leaving the single market and customs union.
Transport Secretary Grant Shapps said extending the plans beyond December 31 st would “add fuel to the fire” by adding additional uncertainty.
Scotland’s first minister Nicola Sturgeon, said it would be “unconscionable” to include a no-deal exit from the EU’s trading plans to the present difficulties triggered by the mutant coronavirus strain.
Trade has currently been disrupted after France prohibited hauliers travelling from the UK due to fears over the spread of the more infectious stress of coronavirus.
However Mr Shapps stated firms currently understood that modification was following December 31 st and had actually been told to plan for it.
He told BBC Breakfast: “I believe the something which might in fact include fuel to the fire would be ending something that everyone’s understood is ending for a very long time, which is the end of the transition duration which completes on December 31, so absolutely not, no.
