Jutting out into the wild Irish Sea, the remote islet of South Stack off Anglesey is a conservation wonderland. Guillemots, puffins and razorbills nest on its vertiginous cliffs.

Such an untouched natural haven requires little upkeep, you might suppose. So I raised an eyebrow when I read that the RSPB, one of the wealthiest charities in the UK – with annual revenues of £170million – had received a grant of £3,353.90 from the Welsh taxpayer to maintain their South Stack site.
