This question resolves YES if the Elgin Marbles (aka the Parthenon Sculptures) are returned to Greece by the end of 2023, and NO in all other cases.
The method of return does not affect resolution; the majority of the collection entering Greece on loan, as a gift, after being stolen, or after the UK being annexed as a Greek colony would all resolve YES.

The BBC reports that a former UK Culture Secretary is now chairing a new board to return the Marbles to Greece, and that the chairman of the British Museum has confirmed a deal will be done. However, it is currently illegal under UK law for the British Museum to dispose of its collection and the current government has stated that it has no intention of changing this law.
