The Customs Union locks out food and other produce from the developing world. It would prevent us, as it does now, from enacting anti-dumping laws in order to protect the British steel and other industries. It would forbid, as it does now, individual trade deals with the BRICS and other countries, including the desperately necessary integration of every part of this country into the Belt and Road Initiative.
Yet by the end of this week, however dressed up or dressed down, membership of the Customs Union will be the policy of both parties. The Labour MP here at North West Durham, a solidly Leave-voting area, is not merely a broad supporter of Jeremy Corbyn's. As we have already seen in relation to his words without actions on the issue of the Teaching Assistants, she is an uncritical supporter of Jeremy Corbyn's.
