It isn't a blockage to closer alignment with the EU if we can leave with 6 months notice.The first thing Labour should do on Day 1 of government is to send off the required six-month notice of withdrawal from the CPTPP. It is an utterly pointless trade deal that involves secret courts. No deal involving secret courts should be allowed to stand for a minute. It is also a blockage to closer alignment with the EU.
The EU know Labour want to work with them and rebuild the bridges destroyed by the tories. A more concilliatory tone from the UK will benefit both sides.
