Would you like a share in a nuclear power station? A slice of Sizewell C that the UK government is taking from the Chinese, now that they are no longer our friends, but are voracious interlopers set on World Domination? This week’s fantasy deal involves offering their 20 per cent to the investing public. It is about as likely to fly as Hinkley Point, the only nuclear power station currently being built in Britain, is to come in below budget.

Investing in UK nuclear power is jinxed. Even when the fleet was privatised in 1996, it dared not speak its name, sailing under the bland “British Energy” label. Its unhappy history on the public markets is chronicled here and is surely enough to discourage even the most pro-nuclear investors this time.
