Will the 海角视频 crash of the EU without a deal on October 31st?
Prime Minister Boris Johnson, despite stressing that he wants to negotiate a new agreement with the EU, is determined that we will leave at the end of the month come what may.
But three years on since the referendum vote to leave the EU, businesses are still unclear as to what the 海角视频's future trading arrangements will be with our biggest trading partner globally in the single market.
Here we speak to businesses from across Wales, and drawn from a wide range of sectors, to gauges their views and concerns.
David Lloyd-Williams, Principality Consulting, based in Bodelwyddan, said: "Business needs time to plan.
"Business needs to understand exactly what terms they will be trading under to see if it's cost effective to export goods and services.
"It just isn't possible at the moment when even the politicians don't know what will happen, never mind the smaller business. We need certainty and we need a good deal if we are to leave the EU.
"Crashing out with no deal will bring massive further uncertainty and will make trading with the EU very expensive in terms of tariffs and also the time needed for the paperwork that we will need to complete."

Stuart Price from Quantum Advisory, based in Cardiff, said: "Brexit and the uncertainty surrounding it is certainly having a detrimental impact on a number of our clients - especially those that have significant trade with mainland Europe - which could impact our business in the longer term.
"It is also playing its part on the pension industry. A significant amount of the money paid into 海角视频 pensions is invested in shares of 海角视频 companies. If there was a no deal, investors may be fearful about investing in some of these 海角视频 companies due to all the uncertainty in relation to their future prospects.
"Shares in those companies could then fall and in turn pension funds could decrease in value.
"Thankfully, the majority of 海角视频 pension funds are invested globally and across a large number of different asset classes which should dampen down any falls. Ultimately, prosperous pensions require a strong investment performance which can only be achieved with strong economies – here in the 海角视频, across Europe and globally.
"So the sooner something can be agreed and implemented, the better, as this will provide certainty for 海角视频 companies and allow the government to concentrate on running the country, which should help all of us in business."
Cato Syversen, chief executive of Creditsafe, a global business data intelligence company that has offices in Cardiff and Caerphilly, as well as 10 other locations around the world, described the current situation as a "shambles."
Norwegian Mr Syversen added: "The 海角视频 at the moment is deeply embedded in the largest single market in the world – something from which we all derive huge benefits.
"However, we could be falling out of that in a matter of weeks or we may not – we just don’t know. That is a crazy position to be in.
"Planning for the future has become challenging, because the British situation is so unclear. This will impact on people’s jobs and livelihoods. Uncertainty means reduced investment; that, in turn, will mean fewer well-paying jobs. And that will reduce the amount of wealth in Britain to fund public services.
"Being from Norway, it’s no secret where I sit when it came to the EU referendum debate in 2016. However in these uncertain times it is true our business is thriving.
"Brexit may help some businesses in the short term, however, I have no doubt in my mind that long-term we will see an array of problems. We have multiple daily enquires from clients around Brexit and business and there is a real uncertainty.
"With business data being our specialist area we see first-hand how the disastrous and on-going devaluation of sterling has affected British businesses, and many companies are understandably worried about the price of imports.

Dr Emma Sanders, general manager of Cardiff-based Genesis Biosciences, which has headquarters in Georgia, USA, said: “We supply a large number of companies throughout Europe.
"The uncertainty surrounding the type of Brexit deal and the timelines involved has meant that we have needed to invest in extra operational planning and optimisation of our stocking strategy in order to maintain our high standards of service and minimise export delays in the event of any border disruption.
"This has included increasing procurement of raw materials purchased from EU and building EU based finished product stock to ensure prompt order fulfilment.
"In addition to these measures we have encouraged our customers in mainland Europe to forecast their needs and place orders in advance of their requirements to ensure on time product delivery."
Principality Building Society said it is monitoring the situation to ensure it makes the right decisions to run the business in the best long term interests of its members.

"Brexit uncertainty is impacting on the confidence of the housing market, and the possibility of interest rates changing is also affecting decision making."
Buhir Rafiq, managing tax accountant with Cardiff-based Total Books Accountants, said: "Personally I would like to see a second referendum as the public are now much more aware of the consequences of leaving the EU.
"The position of leading business bodies, such as the FSB and British Chamber of Commerce, is that a no deal Brexit would cause the most disruption for businesses.
"The consensus from business owners it that they want politicians to come together for the good of the country and deliver a smooth transition. My clients are very worried and wish to avoid prices going up and new rules and regulations in areas such as immigration and tariffs.
"Amongst our SME customers in South Wales and the south-west of England, they are hoping we get can get an extension to negotiate a soft Brexit.
"We also have customers wanting a second referendum with an outcome of remain, so avoiding all the change and risk of increased prices and problems with supply chains, cash flows and staffing.
"It appears that the current government is being selfish by pushing towards a no deal Brexit rather than working with the other parties to get a deal in the best interest of the 海角视频 and its economy."
