George Osborne even threatened that there would be a most savage emergency budget the day after. 

This preposterous Project Fear budget would have included spending cuts worth £15billion, a £15billion tax hike and a steep rise in the basic rate of income tax. 

Well, as Sunday Express readers will recall, the economy did not go into a slump. 

Instead it has continued to confound those Remain doom-mongers and grow.  

For as all the latest figures show, record numbers are now in work and the numbers of workless households has fallen to the lowest levels for a generation. 

Indeed, the latest post-Brexit figures show that industrial production has risen for six months in a row (the last time that was achieved was 23 years ago). 

Manufacturing output also rose higher than expected. 

Remember, many of these doom-mongers were the same people who told us 18 years ago that we would be punished severely if we didn’t join the euro.  

Yet just imagine what a mess we would be in if we had. 

To illustrate how wrong they were: since the euro was formed, the UK has managed cumulative growth of 40 per cent while the Eurozone has managed only 28 per cent growth. 

Despite all the gloom-laden predictions of how terrible life would be after Brexit, a survey of business executives from around the world ranked Britain third behind the United States and China as the top investment destination, well ahead of Germany and France. 

In fact, with nearly 90 per cent of our economy dependent on business beyond Europe, perhaps we can see why we are such an important investment destination. 

Interestingly, it is the EU which heavily relies on the UK.  

For example, more than half of the EU’s asset management and capital markets are run by British firms and UK banks provide loans equivalent to 10 per cent of the EU’s entire economy. 

Yet despite all the evidence on how much the EU needs the UK, not just on financial services but also because we buy so many of their products, the Commission’s top priority for Brexit negotiations has not been trade but money and, to be precise, extracting as much as it can out of Britain. 

All the talk about requiring “sufficient progress” on citizens’ rights and Ireland has, of course, been a crude smokescreen to try to force the UK into paying a huge “divorce bill”. 

Yet we should be optimistic, for the EU has much more to lose if it doesn’t forge a trade deal with the UK.  

After all, the UK is the single largest export market for it and any money we may have put on the table to settle any legal obligations would be taken off the table if it makes no trade deal with us. 

So to confound all the negative rhetoric coming from a small number of people who can’t seem to accept the result of the referendum, we should focus on the very real benefits that will come to us when we leave. 

A recent paper by a group of influential economists made clear that when the UK leaves, we will be able to get tariffs down on goods which cost us more at the moment. 

This will dramatically assist the poorest, as the highest EU levies are set on products such as shoes, clothing and footwear which affect struggling households as they spend most of their income on these.  

Furthermore, these economists, who have a better record in many ways than the Treasury, predict that once we are out and in control of our trade relationships, the windfall could be as high as £135billion by 2020-2025. 

So there are, despite the professional doomsters, many reasons to be cheerful about our prospects. 

After all, we are the fifth largest economy in the world, with the world’s most important finance centre.  

We have the world’s fourth most potent armed forces and a global network through the Commonwealth which is unrivalled in its reach. 

The British people weighed all that up and they decided in vast numbers that they wanted to take back control of our laws, our money and our borders, to ensure that we could take advantage of the opportunities which will flow from our newfound independence from the EU. 

That is why we should be cheerful about the fact that, on March 29, 2019, we will leave the EU.
