Final thing on this thread, given it got lots of attention - there& #39;s obviously more important things to be thinking about right now! A key point though is that the fundamental argument I made is the same argument @NicolaSturgeon & @Feorlean make on Brexit. (new short thread 1/6) https://twitter.com/JohnFerry18/status/1271379724632236032">https://twitter.com/JohnFerry...

I identify an economic separation cliff edge & extrapolate from there real-life implications of going over it. The difference is that the cliff-edge from Brexit relates to creating self-imposed trade friction upon overnight withdrawal from the customs union & single market. 2/6

With & #39;Scexit& #39;, the cliff-edge comes from removal from UK monetary & fiscal systems. Brexit has a transition period, but trade independence happens overnight. It& #39;s the same with the monetary & fiscal aspects of Scottish secession. 3/6

There might be a transition period, but economic secession would still take place overnight on secession day. One minute we& #39;d be in, the next out, and that would have enormous implications for our economy. There is therefore an economic cliff edge - and it& #39;s a big one. 4/6

It& #39;s no more hyperbolic or unreasonable to outline how this would lead to a crisis than it is to point to economic Brexit at the end of this year & warn people that the new customs border will lead to queues of lorries at Dover & just-in-time manufacturing coming to an end. 5/6

For senior SNP politicians to highlight these Brexit dangers while pretending Scottish secession would be smooth & without major risks is utterly disingenuous. If we care about our country & its people then we can& #39;t let them away with that. #ForScotland 6/6
