What prospectus?

Mary Thomas (Letters, May 17) describes the SNP'S Growth Commission as “outdated”. The SNP prospectus for independence in 2014 was “outdated” as soon as the Nationalists lost the referendum. It, of course, had oil revenue “baked into” the figures. When the price of oil plummeted the Growth Commission produced a report downplaying the potential proceeds from oil. But like its predecessor it too was jettisoned almost as soon as it was printed, in its case because it painted a too gloomy – but accurate – picture of what independence would look like.

It will be some time before the SNP'S current prospectus for an independent Scotland will be binned – because to date there isn't one. Ms Thomas really needs to get up to speed, though I do sympathise with her difficulty in keeping up with the dizzying number of SNP U-turns. She has reverted to pinning her hopes on oil, seemingly unaware that the SNP, along with their Green nationalists, wish to turn their backs on oil and leave it in the ground.

But what do I know? Perhaps oil has already been given a reprieve now that its price is back up. We have witnessed the SNP'S virtuosity in performing the hokey cokey in relation to the EU and Nato.

I am also puzzled by Ms Thomas's claim that shipbuilding has been “consigned to history” by the UK government's lack of investment. Does she not know it has been "saved” by the SNP, which is investing in it to the tune of £240 million and counting?

Perhaps Scotland would be “the richest country ever” to become independent. What worries me, however, and a majority of the Scottish people is – what happens after that?
