Edward O'Hara: MP for Knowsley South

There has been a long-running debate as to the future of the sculptures, which once formed a frieze on the front of the Parthenon in Athens.

The 14 MPS, including former minister and chairman of the Commons works of art committee Tony Banks, said a �29m museum is under construction in Athens for the occasion.

"This gallery will remain empty as long as the Parthenon Marbles are not available for display in it," the motion said.

Removal

"(This House) is concerned that this will bring great discredit to the British Government and the British Museum."

The 56 sculpted friezes are housed at the British Museum where they were sent after their removal from Greece during Ottoman Turkish rule

They are known in Greece as the Parthenon sculptures and date from between 447 and 432 BC.

The sculptures were removed during Ottoman Turkish rule

They depict the most formal religious ceremonies of ancient Athens - the Panathenaea procession.

In 1799 the British ambassador to the Ottoman Empire, Lord Elgin, removed the friezes and brought them to the UK.

The Greek Government has long fought to have the artefacts returned and remains willing to make periodic attempts to overturn Britain's claim that its possession of the marbles is legitimate.

In August the Greek Culture Minister Evangelos Venizelos said international pressure would mount ahead of the 2004 Olympics for them to be given back, even if only on loan.
