Whether the UK intends to do so or not, I cannot say - but I hope that the Marbles stay put. The record of UK governments in defending the interests of the UK since September 1945 is urine-poor, to put it mildly. As for the argument that the Elgin Marbles were "stolen": they were not. Lord Elgin sought and obtained permission from the Sultan of Turkey to remove them (Greece, at the time, being a province of the Turkish Empire). To those folk who speak of the "oppression" of Greeks by Turks: it was no worse than the continuing oppression of true (i.e. pre-Columbian) Americans by those who have usurped those two continents, then raped, tortured, mutilated, and killed their way through the native peoples. I don't hear anyone calling for the New World to be vacated of the descendants of Old Worlders...? Make the President of the USA give up his place in favour of an "Injun"? Much as I would applaud the move, it would be a cold day in Hell...
