The British Museum is engaged in "constructive discussions" over the possible return of the so-called Elgin Marbles in an exchange with Greece.
Last year it emerged negotiations between Greek authorities and the museum chairman, former Tory austerity Chancellor George Osborne, over the 2,500-year-old cultural treasures were at an "advanced stage".
The sculptures could now be loaned to Athens under a long-term "cultural exchange" programme, according to the Daily Telegraph, as UK law prevents museums from giving away artefacts.
