Human rights barrister Amal Clooney has called on Britain to give up its "intransigence" and start talks with Greece on the return of the Elgin Marbles.
The battle for the Elgin Marbles has become one of the most contentious cultural disputes in recent history.
"This is an injustice that has persisted for too long, and in a world of intractable conflicts," the new wife of Hollywood star George Clooney said.
"Here is one that can be solved in a way that can benefit both parties and humankind altogether.
"The Greek government is in the right to ask for the return of the marbles," she told journalists as she stepped into her first post-wedding job this week.
