As is written in the Warships1.com database:
left Portsmouth Mar.12/47 but broke tow Apr.23/47 on way to breakers
ran aground in Prussia Cove off Cornish coast
scrapped where she lay 1947-1956
As to what remains of her... Well I guess nothing (assuming they scrapped her completely).
Since she was broken up on the spot where she ran aground, it could have taken longer to scrap her due to difficulties accessing her. But I'm not sure. Does the "1947-1956" mean she was scrapped somewhere between 1947 and 1956 or does it mean they start scrapping her in 1947 and finished with the job in 1956 ?
It might be that scrapping a ship in a dock might go faster than when it is stuck on the rocks, but I'm not sure about that. But I think you might have better acces to a ship's hull in docks than on the rocks.
