Can anybody tell me why my friend's potatoes are so distorted please? They
have what is almost a warped swastika shape deeply embedded in the tuber.
They are rocket potatoes and ones at another end of the allotment are ok.
There are miniscule white grubs in the ones she found today. I can only
find watering or cold problems in the RHS book.

I would call that a watering issue, specifically heavy rain after a dry
period, causing them to swell and burst the skins, as happens with a lot of
crops. The white grubs are a separate issue.
