We are now 100 days on from the EU referendum result, and the utter lack of clarity from the Prime Minister and the rest of the UK Government is a shameful abdication of responsibility.
The Tories are in the process of walking the UK economy off a cliff with a vague promise that they'll find a parachute on the way down. It's not good enough.
People in Scotland voted overwhelmingly against leaving the EU - but even Leave voters must be worried by Theresa May's inability to outline even the basics of what 'Brexit means Brexit' actually means.
Today the SNP is publishing 100 Brexit questions 100 days on - it is by no means an exhaustive list, but is shows the sheer scale of uncertainty facing Scotland and the rest of the UK. The Prime Minister is today set to address the Tory conference on Brexit - she needs to take the opportunity to start delivering at least some of the answers.
Theresa May's Brexit ministers are more interested in post-Empire fantasies about commissioning new Royal yachts than doing the hard work required - and this casual approach is putting jobs, investment and economic prosperity at risk.
Trade
1. Will the UK still be a member of the single market?
2. If not, what will the terms of the UK's access to the single market be?
3. Will the UK remain a member of the European Union Customs Union?
4. Was the establishment of the Department for International Trade an admission that the UK has no intention of remaining a member of the European Union Customs Union?
5. Will the UK have to make a financial contribution to the EU?
6. In the Holyrood debate of 30th June 2016 Ruth Davidson said: "Retaining our place in the single market should be the overriding priority." How will the Tories ensure that Scotland remains in the single market?
7. What preparatory work has the UK Government done on the tariff agreements that would be required with the EU and other countries in the event of being outside the single market?
8. Will businesses be able to continue to trade with the EU without customs checks or other administrative costs?
9. Has the UK Government discussed proposed new trade arrangements with the WTO?
10. What guarantees has the UK Government sought or received from other nations that punitive tariff levels will not be imposed on UK produce - such as steel exports - in the event of not being in the single market?
11. Has the UK Government produced any estimates of the likely impact of Brexit on inward investment levels?
12. Has the UK Government spoken to the Japanese Government about the report it published on Brexit, and what guarantees have been sought regarding Japanese investment in the UK?
13. Has the UK Government engaged with the US Government regarding President Obama's remarks - made both prior to and after the EU referendum - that the UK will now find itself "at the back of the queue" when it comes to US trade priorities in Europe?
14. Has the UK Government opened discussions with the United States on a post-Brexit trade agreement?
15. What does the UK Government conclude from President Obama's remarks about the future of the so-called "special relationship" with the United States?
16. Are the talks held by the UK Government since June 23rd with non-EU nations regarding bilateral trade deals in breach of the UK's still current EU treaty obligations? And if so, is the UK risking financial penalties and fines from the EU?
17. On 5 June 2016 the then Prime Minister David Cameron said: "Those campaigning to leave Europe are inviting the British people to make an extraordinary choice - to be the first major economy in history to deliberately choose a second-rate, more restrictive trading relationship for its biggest market..." Why do so many Conservatives who supported 'Remain' now enthusiastically 'choose a second-rate, more restrictive trading relationship for [the UK's] biggest market'?
18. On 18 April 2016 the then Chancellor George Osborne cited treasury analysis saying every household would be £4,300 a year worse off and that the effects of Brexit meant "Britain would be permanently poorer. Britain's families would be permanently poorer too..." How much poorer do the Conservative party believe people in Scotland will be if we were to be pulled out of the EU?
19. On 26 May 2016 Tory MSP John Lamont said that the European negotiating position has allowed international trade agreements that have opened up new markets for Scottish produce but that "We do not know what the alternative would be if the UK voted to leave". Can he or the Conservatives now tell us what the alternative is since they now appear to be backing Brexit?
20. On 21 June 2016 Ruth Davidson said: "Basic questions over restrictions, tariffs or the ability of British workers to operate abroad are dismissed instead of answered...'Out' doesn't just fail the certainty test." Now that she appears to support Brexit what "certainty test" has she met to ensure there will be no such restrictions or tariffs if Scotland were to be pulled out of the EU?
21. On 22 June 2016 Theresa May as Home Secretary warned people in Northern Ireland that there could be "tariffs on exporting goods into the EU" if we're out of the European Union. What level of tariffs do the Conservatives think will be levelled on Scottish goods if Scotland were to be pulled out of the EU?
22. Before the EU referendum vote the Scottish Secretary David Mundell wrote: "Hundreds of thousands of jobs in Scotland depend on having access to the EU's single market. What would happen to the families who rely on those jobs for their livelihoods if we were to pull out of the EU?" What would happen to those families who rely on those jobs if Scotland were to be pulled out of the EU?
23. On 31 May 2015 the then Prime Minister David Cameron warned Eurosceptic Tories that quitting the EU would leave farmers facing punishing tariffs on their exports. He said: "It's for [Eurosceptics] to look those farmers in the eye and tell them if they're going to have to pay tariffs and, if so, how much." How much will Scottish farmers have to pay in tariffs if Scotland were to be pulled out of the EU?
24. Before the EU referendum vote David Mundell wrote: "A vote to leave would trade in our power and influence as the EU's second largest economy for the weakness and irrelevance of observer status". Why does he now support "the weakness and irrelevance of observer status" that will come with Brexit?
25. Before the EU referendum David Mundell wrote: "Others say that losing our free and unrestricted access to a single market of 500 million people...will leave us no worse off. That sounds to me like it's too good to be true." How "true" is it now?
Economic impact
26. What work has the UK Government done on the overall impact of Brexit of employment levels in the UK?

32. Has the UK Government conducted any formal or informal negotiations about EFTA membership?

34. On 28 June 2016 Ruth Davidson said: "I am absolutely sure that my role is to ... help [get], particularly in my patch of the world, passporting for financial services". Does she still support getting passporting for financial services and will she support free movement to retain it?
35. What substance is there to suggestions that the UK Government is prepared to agree a continued single market for bankers and the financial services sector alone?
36. On 6 June 2016 the then Prime Minister David Cameron said a 'Leave' vote would "put a bomb under the economy...[and]...we'd have lit the fuse ourselves". How will the Conservative party defuse this metaphoric bomb under our economy?
37. What impact will leaving the EU have on tax revenues?
38. What impact will leaving the EU have on UK GDP?

Personal finances
68. Before the 23rd June vote David Mundell wrote: "All the economic experts predict that the potential damage a Brexit would do to jobs, mortgages and the economy as a whole across Scotland is just too severe." How "severe" will Brexit be for jobs, mortgages and the economy in Scotland if Scotland were to be pulled out of the EU?
69. In his article of 23rd June 2016 David Mundell wrote: "...when Remainers ask...how a collapse in the stock market will impact upon people's pension pots...we deserve to have answers from the Vote Leave campaign." In light of reports that Brexit has caused greater deficits in pension funds, with gilt yields at historic lows, can Mr Mundell tell those pensioners how Scotland being pulled out of the EU will be good for their pensions?
70. On 11 June 2016, Ruth Davidson said: "It's clear that following the fantasy economics of the Leave campaign would put this universal dream [of buying a first home] at risk. Families...can't afford a vote to leave." How will she protect this "universal dream" and how could families in Scotland afford a home if Scotland were to be pulled out of the EU?

72. What guarantees can the UK Government give on support for farming beyond 2020?
