Singham: I’m not suggesting that we leave without a deal – we should follow the proposals I’ve outlined. But if we did, for whatever reason, there will be temporary disruption – and part of that disruption will be down to the government’s lack of preparation. It’s certainly possible to prepare for No Deal. Many other countries are more prepared than us, such as the Dutch, who have made lots of customs preparations. To not prepare adequately was a deliberate choice by our government. The only reason not to upgrade our customs facilities was if the government was planning all along to remain in the EU Customs Union.
