In recent questions to the Treasury, I asked the Chancellor to explain why the Customs Union is the wrong policy choice for the future strength of the UK economy. He explained his belief that the Prime Minister negotiated a deal with the European Union which gave us many of the benefits of being in a customs union, while preserving our ability to conduct an independent trade policy. He continued, saying that the Government put that deal to the House three times and it was defeated three times, so we have to pursue other options - alas, I disagree with him profoundly on this, as an independent trade policy is where the benefit of our leaving the EU can be found in terms of trade, jobs and opportunity. The Customs Union really is the wrong policy choice.
