Still hard to see how Brexit really impacts Tesla or TSLA. But since you raised it and with an underlined
Off Topic applied...
FC is correct - there is currently no parliamentary majority for a second referendum and it's increasingly tough to see one arising. Even if there were one, none of the the UK government, the official Opposition, nor any likely new leader of the Conservative party supports a second referendum. The Prime Minister has wedded her legacy to delivering Brexit and the leader of the Opposition is a hard socialist / communist, who almost certainly secretly voted for Brexit - EU membership is incompatible with key planks of his policy agenda on state intervention.
Unless the Executive is prepared to back an Act of Parliament necessary to legislate for a second referendum, there is no procedural mechanism for one to occur. If I am wrong about the government's intentions and at the last minute it does implement a 12-month delay to Brexit pending a repeat referendum, my view of the British social psyche is that there would be a bigger majority for Brexit than in 2016. That'd be a question for 2020 however.
FC is also correct that a WTO Brexit (what is termed by many as a "No deal Brexit") is the default legal position. Unless a new Act of Parliament is passed stipulating something else, this is what will happen, as currently scheduled on 29 March 2019. Whether this is the most likely outcome at this point is hard to say. There is brinkmanship on all sides, both within the UK Cabinet, parliament and at the European level. The "deal" on the table will almost certainly not pass the initial parliamentary vote on c. 15th Jan, with a massive rather than narrow defeat for the government quite likely.
What happens next largely depends upon whether the EU side are willing to re-open certain terms for discussion to prevent economic fallout for their own citizens, or would rather set an example of the UK. I say this because within the UK, the parliamentary mathematics suggest that the government is perversely more likely to fall if the deal is passed than if it's rejected - the govt relies upon the Northern Irish DUP for its majority. The DUP are to their core, ideologically opposed to the existing deal and would bring the govt down rather than see it passed in its current form. The vote on the 15th Jan is only an indicative vote and an Act of Parliament is still required to implement it, so plenty of time for them to cause political mischief even if the deal is passed in the initial vote on 15th Jan.
It's very hard to say with confidence what might be the most likely outcome at this point and anyone that says they know is lying. If you put a gun to my head, I'd wager that there may be a delay to Brexit of a few months, followed by a negotiated WTO exit. So a "No deal" on trade but with a series of Deals on various policy areas that matter most to both sides (e.g. airspace / overflight rights, passage of radioactive material, criminal record sharing etc...), with the further time used to implement larger customs facilities at the key ports. Needless to say, UK politics (and consumer demand / business sentiment) would be pretty turbulent during this period but life would go on.
The bizarre thing in all this is that even if the UK brexits without a trade or customs agreement, both the UK and Irish have said they will not impose a visible border between Eire and Northern Ireland. And there's good reason for this - there would certainly not be any political or popular appetite to deploy the troops necessary to enforce one. But yet the reason why the Withdrawal Agreement is unlikely to pass the UK parliament is almost squarely due to the terms designed to prevent the need for a visible border on the EU's Irish frontier (the much discussed "Irish Backstop").
If you're not going to implement a visible border anyway, then it would be in both sides' rational interests to sign a mutually beneficial trade deal and manage the smuggling risk of third country of origin goods in a sensible rather than dogmatic way. But politics is not always rational and a "hard Brexit" may be a necessary precursor to the trade deal if the brinkmanship on either side oversteps the line.
Anyway, go Tesla. An accelerated construction timetable for a 100%-owned plant in the biggest car market in the world. Far more important than what happens with Brexit.
The UK is not the decision maker and has no power to extend the clock: it's the EU, and the EU made it clear they are not renegotiating, nor waiting for a referendum with uncertain wording and uncertain outcome. (Which is the right EU decision.)
These UK political figures still talking about a new referendum are disinformed, delusional or are grandstanding.
It's similar to the Greek EU referendum that was mooted by the time it was held.
BTW., the January 15 vote will very likely go against the UK government, which makes a no-deal Brexit the most likely outcome currently.
Numerous major political figures in the UK have publicly disagreed with this sentiment. Over 100 MPs have already signed on to a policy of supporting a second referendum. Far from a majority, but of course the vast majority have not committed themselves either way in advance of voting on May's proposal.
FT's analysis of timing is:
"Would there be time to hold a second referendum before exit day in March 2019? The UK would have to seek an extension of the Article 50 process from Brussels. Many EU experts believe Brussels would agree to this. However, a referendum to resolve the UK’s status vis-à-vis the EU would almost certainly have to be held before the European elections in late May next year."
Yes, those are the three options that would need to be voted on.
