Oh no, I've finally got round to reading this properly having seen others comment a bit on it.
Corbyn is largely right about May's deal, but his alternative plan is just total fantasy. A solid bar cast of purest Unobtainium.
First an aside on the backstop. Corbyn is entirely right that it can't be ended unilaterally, but I really don't know what people expected. There has to be a backstop for there to be a Withdrawal Agreement, as the future relationship will be negotiated after Brexit. 2/ pic.twitter.com/gRP2MsvvFz
Even if you are planning a future relationship that would mean an invisible border in Northern Ireand, there's no guarantee that there'll be an agreement. A backstop is for then, and if it can be unilaterally ended, it's not a Backstop. 3/
