So four days on and the fallout from Brexit continues to swirl and what have we learnt?
Rather than be any clearer on what will happen next, politically and financially, if anything, arguably the quagmire appears to have deepened.
Prime Minister Cameron makes a statement
Addressing the House of Commons this afternoon, the Premier said the decision of the referendum was clear and "must be accepted" and the process to leave the EU begun, although it was not the result he had wanted.
This will be a difficult process, with challenging and complex constitutional issues.
A special unit drawn from across the UK civil service will be drafted in and will advise the cabinet as this process unfolds on the best way to achieve what the UK wants from the exit, he explained.
"This is our sovereign decision," he told the house.
The country should take confidence, he added, in the fact that this being approached from a position of financial strength and that the systems in place are more resilient than they were six years ago.
The pound plunged 10% on Friday and has now fallen more today to US$1.3218 - a new 31 year low- as the global economy and markets looks at Britain's currency and sees uncertainty and potential recession ahead.
It came as Boris Johnson, the main man in the frame to succeed David Cameron, and to be the one who fires the starting gun on a withdrawal from the EU, had said the pound was stable.
Chancellor George Osborne seeks to reassure
It also comes as markets continue to slide. Friday's FTSE100 close prompted many to say the decline had not been so pronounced, though it was still over 3% and today the premier index dropped another 120 points, or almost 2%.
Before London opened, Osborne, who has been conspicuously absent since the vote, had sought to calm fears but the extent of what he can do is somewhat limited.
He started with the premise that the UK economy was in a "position of strength" and as expected parked an "emergency budget".
He made reference to the BoE, which has already pledged to provide an eye-watering £350bn of stimulus capital to prop up the market, but the power of Central Banks these days is perhaps fading?
But analysts suggested Osborne's intervention had had little effect.
Connor Campbell, at SpreadEx, said: "Initially the FTSE had (relatively) held its ground, the index somewhat boosted by George Osborne’s attempts to reassure the markets.
"However, it seems that the impact of the Chancellor’s charms were short-lived, the FTSE almost doubling its losses to 1.5% as lunchtime approached. The pound, meanwhile, made the FTSE’s losses look positively meagre, with cable diving another 2.8% to hit a fresh 31-year low of $1.325."
Michael Hewson, at CMC Markets, said: "While the Chancellor’s measured tone appears to have helped alleviate concerns about a rudderless UK ship, concerns about the banking sector continue to be a pressure point for investors, as dark threats about the removal of financial pass-porting continue to weigh, and yields continue to fall.
"This has prompted further selling of banking stocks which have continued to remain under pressure with Royal Bank of Scotland and Barclays continuing their Friday slides."
EasyJet and Foxtons issue profit warnings; others shrug Brexit off
Budget airline EasyJet (LON:EZJ) and estate agent Foxtons (LON:FOCT) both issued profit warnings this morning, and are both saw share prices crash around 20%.
EasyJet warned that the outcome of the UK's EU referendum would hit second-half revenue, while Foxtons said the run-up to the EU referendum led to significant uncertainty across London housing markets.
It said the decision to leave Europe was expected to prolong that uncertainty and the second-half upturn it had foreseen was now unlikely.
However other firms have shrugged it off. For example, plastics specialist Symphony Environmental Technologies plc (LON:SYM) said the UK’s decision to leave the EU on Friday will not adversely affect the business and the group was on track to meet market expectations.
Negative interest rates?
Elsewhere, Hargreaves Lansdown noted today that the swaps market was now pricing in a 15% chance of UK interest rates turning negative over the course of the next year, on the back of the EU referendum result.
The market is now also giving a 50% chance of an interest rate cut in July, a 65% chance of a cut by August, and an 80% chance of a cut by the end of the year.
"The Bank of England may soon find itself between a rock and a hard place, if the economy and inflation start pointing in different policy directions.
"That’s because although the Brexit vote has increased economic uncertainty, it has also taken a toll on Sterling, which is likely to feed through into inflation because it makes imports that much more expensive. This raises the uncomfortable prospect for the central bank of cutting interest rates while inflation is rising, something it has proved it is willing to do in the past in order to boost the economy."
