In recent days, two rather contradictory messages have been spread on the subject of Brexit.
First, Nissan Motor company's chief executive, Makoto Uchida, who was initially very critical of his Brexit, said that the impact of his Brexit on the company's business in the UK is now negligible.
He said that he called on the country to be more optimistic about its future prospects. A £2 billion refurbishment of the Sunderland plant has been announced, confirming that the UK will become Nissan's main sales base in Europe.
European Commission President, claimed that her generation of politicians had “goofed up” over Brexit. The upcoming one should fix it and put Britain firmly on the path to rejoining.
It is certain that the Remain camp's short-term predictions about the referendum turned out to be spectacularly wrong.
After the June 2016 vote, the UK was predicted to be in deep recession by the end of the year, with unemployment rising by half a million people. In fact, in the second half of 2016, GDP grew at a respectable 2% annual rate and unemployment fell.
But how do we stand now, over seven years after the decision to leave?
The estimates of GDP published by the OECD in Paris tell a revealing story. Between the second quarter of 2016 and the most recent figure for the third quarter of this year, the British economy only grew by 9.1 per cent.
The figure, amounting to not much more than one per cent a year, is disappointing. This is why both Rishi Sunak and Keir Starmer have placed the aim of raising the growth of both output and productivity centre stage in their policy objectives.
In Spain, however, growth over the same period was a bit less, at 8.3 per cent. In both France and Italy it was even lower, at 5.5 and 5.3 per cent respectively. Perhaps Germany, the poster country for many Remainers, can alter the story? But no. GDP there rose by just 6.2 per cent.
The manufacturing lobby makes a lot of noise, almost portraying Brexit as a catastrophe for the sector. The positive pronouncements of companies like Nissan do not seem to dampen the relish and enthusiasm with which this narrative is set out.
But it is Germany rather than the UK where manufacturing has performed really badly since Brexit. Again using OECD data, here in the UK output has grown by 7.6 per cent. True, lower than the economy as a whole. But in Germany, manufacturing output is actually six per cent lower than it was in the first half of 2016.
The American economy offers a fairly sharp contrast. From the first half of 2016, GDP in the US has risen by 18.2 per cent, a respectable annual rate of some 2.4 per cent.
An even better performance has been registered by Poland. Since the Brexit vote, the Polish economy has grown by 25.6 per cent. This annual growth rate of over three per cent would go a long way to solving the problems with the public finances which face the British government, whichever party is in power, both now and after the election.
Of course, countries like Poland are still in the phase of playing catch-up with Western economies after spending decades in the centrally planned Soviet bloc. But they are carrying this out with admirable levels of entrepreneurial drive which we would do well to emulate.
What is abundantly clear is that there are no real lessons to be learned from the longer standing member countries of the EU. Since Brexit, the UK has outperformed them.
