According to that newspaper report, it was estimated (earlier in the year) that heating the pool would cost £13,000 a year. That is one heck of a lot of energy.
Meanwhile, we are being prepared for possible energy shortages over winter, and plans to close things like large railway stations, libraries and other public buildings for days at a time, should these shortages arise, are being considered.
I sincerely hope that if there are energy shortages, Sunak will have the moral decency to refrain from heating that pool. It would be crass of him, as someone who has played a large part in the devastating economic crisis that is developing, to squander energy like that, while those who can't afford to even heat their homes won't even be able to go spend the day keeping warm in the libraries!
I can already imagine the cartoons that would appear in the newspapers.
Sunak will be luxuriating in a steaming-hot pool, while hoards of wretched, shivering souls are hammering on the locked doors of a library, begging to be allowed in.
If I were any good at art, I'd draw it myself!
