First, let me begin by remarking on the number of Brexit articles that have appeared on the BBC site in the last 48 hours or so. This is my personal Nirvana.
Next let me also say that since I have never been before public TV cameras let alone grilled by a seasoned reporter like Jo Coburn, I don't know how I would react under pressure, but the fact is that Jo's question about why the Labour stance is superior to that of the Conservatives and much, much more likely to be accepted by the EU is actually simple and frankly irrefutable. So here goes.
We have a number of parties in the UK all with a stake in this game, and the 27 other countries of the EU, all represented by Messr. Barnier. We know that the Scottish, The Irish, probably the Welsh, Labour, Liberal Democrats are all in favour of a soft Brexit and many are calling for a customs union of sorts. Even within the Conservatives there is a strong contingent that wants a softer break from the EU, and have only stayed together for the dubious pleasure of having Teresa May serve as leader of her Majesty's government for a while longer.
Next, there is a loud (and in my opinion illogical and misguided by their imperialistic principles group, that wants nothing more than a hard Brexit whatever the cost. There response to any EU points of negotiation and even more so to their red lines is. LEAVE -LEAVE - LEAVE.
This viewpoint, however they want to express it, is undesirable by most parties, especially the EU. They claim it strengthens their negotiating position. They are wrong! (I will hold my tongue rather than further express my viewpoint on these people).
On the other hand, we have an EU that is pissed off by the Brits but none-the-less recognizes that having another heavy weight in their midst is worth putting up with all the 'agro' they receive from a non-believer stirring up trouble every now and then. Be that as it may, they recognize danger when they encounter it, far better than the Brexiteers across the channel. They recognize that all the money in the world, all the best deals are meaningless if the deal they strike with Britain is better than the one they had before when they were inside the EU; because then all their members will want a similar one.
Still they are willing to talk, but with conditions. Foremost among these is to protect the interests of one of their own, Ireland - and as such have given up their own view in favour of supporting anything Ireland wants and agrees to do. This 'no customs union, but we want everything that a free trade deal - no border - everybody does whatever the hell they want approach' has to offer, is at best insane and worst downright moronic. Frankly, there is no way that the EU will accept to moving on to the next stage with this offer. This isn't cherry picking, its taking over the cherry orchard!
On the other hand, option B, we have Labour that has now tabled another option. It may be unpalatable to the hard-line Brexiteers but consider what it offers. It offers a solution to the Irish border question (for the most part). It offers a solution to Scottish devolution because (a) Scottish trade interests are protected (b) who gets the powers returned from Brussels is a moot question, because there aren't any!
What's more, and ironically in my opinion, even the business world has sided with Corbyn and you can rest assured that if the UK businesses like it, so will the European. So, like Elvis Presley before, the Brexiteers' hope for support from the business world of Europe has just left the building.
The EU has always maintained that they want a deal with Britain and that a 'no-deal' was one they would avoid as far as is humanly possible. If you think about it, even the BBC can work out that only Corbyn's offer makes it possible to keep talking with a hope of progressing to an acceptable solution.
So Ms. Long-Bailey, if you agree, feel free to use this argument against any future meaningless loaded questions about the superiority of the Labour offer. As for Liam Fox's speech about how it would be a sell-out of the British voter; have you ever noticed that absolutely everybody is an expert on the voter but nobody has the guts to stand up for a "second referendum" (for want of a better term), where you just ask them and learn the public's opinion?
While you are here, perhaps you would consider signing the petition demanding the government give back the final vote on Brexit to the voter. Whichever side of the debate you are on there is no way the politicians will give you what you want. Give the power back to the voter and if they agree with you, you get your way.
