ATHENS/LONDON (Reuters) -Greek Prime Minister Kyriakos Mitsotakis accused his British counterpart Rishi Sunak of cancelling a scheduled meeting in London on Tuesday in a diplomatic row over the status of the Parthenon Sculptures. Greece has repeatedly asked the British Museum to permanently return the 2,500-year-old sculptures that British diplomat Lord Elgin removed from the Parthenon temple in the early 19th century when he was ambassador to the Ottoman Empire. "I express my annoyance that the British Prime Minister cancelled our planned meeting just hours before it was due to take place," Mitsotakis said in a statement.
