Labour leader Keir Starmer said Rishi Sunak had "lost his marbles" at Prime Minister’s Questions on Wednesday as the row with Greece intensifies and the Tory party appears split on immigration policies.
The PM is embroiled in a deepening war of words with Athens after cancelling a meeting with Greek leader Kyriakos Mitsotakis.
Downing Street said the talks were agreed on the basis that the Greek PM would not publicly lobby for the return of the ancient sculptures that are on display as part of the British Museum’s collection. But Greece has denied the claim.
Labour accused Mr Sunak of “stamping his feet” and “petulant walking away”.
Mr Starmer, after an exchange about migration, said: “Never mind the British Museum, it’s the Prime Minister who has obviously lost his marbles.
“The Greek prime minister came to London to meet him, a fellow Nato member, an economic ally, one of our most important partners in tackling illegal immigration.
“But instead of using that meeting to discuss those serious issues, he tried to humiliate him and cancelled at the last minute. Why such small politics, Prime Minister?”
