The dispute centres around the Parthenon Marbles removed by the Earl of Elgin, which are in the British Museum. A few sculptures from the Parthenon are also in the Louvre in Paris, in Copenhagen, and elsewhere, but over fifty percent are in the Acropolis Museum in Athens.[10][80] A few can still be seen on the building itself. The Greek government has campaigned since 1983 for the British Museum to return the sculptures to Greece.[80] The British Museum has steadfastly refused to return the sculptures,[81] and successive British governments have been unwilling to force the Museum to do so (which would require legislation). Nevertheless, talks between senior representatives from Greek and British cultural ministries, and their legal advisors took place in London on 4 May 2007. These were the first serious negotiations for several years, and there were hopes that the two sides may move a step closer to a resolution.
