Kyriakos Mitsotakis says his UK counterpart, Andy Burnham, has been supportive of restitution efforts in the past

The Greek prime minister has vowed to “ramp up” his country’s claims to win back the Parthenon marbles from the British Museum, emphasising that his UK counterpart, Andy Burnham, was hugely supportive of restitution efforts before he moved into Downing Street.

Kyriakos Mitsotakis said he would raise the issue in the strongest of terms when he met Burnham, who was culture secretary in a previous Labour government.
