A team of London lawyers, including Amal Clooney, are in Athens to submit proposals for a new boost to Greece's campaign to reclaim the 5th century BC Parthenon Sculptures from Britain.

Culture Minister Costas Tassoulas said he had had long discussions with Mrs Clooney, who recently married Hollywood star George Clooney, and her two colleagues, on a potential legal bid for the works, know as the Elgin Marbles.

The marble sculptures, which for more than 2,000 years decorated the Parthenon temple on the Acropolis, were removed more than two centuries ago by Lord Elgin, a Scottish nobleman, and are displayed in London's British Museum.

Greece maintains they were illegally removed during Greece's Turkish occupation and should be returned for display in a new Athens museum - which the British Museum and the British Government reject.
