The Unknown Warrior and overseas war graves

Has Britain tried to identify the Unknown Warrior, and who maintains overseas military cemeteries?

The Commonwealth War Graves Commission maintains overseas graves; the participants understand the Unknown Warrior's anonymity to be deliberate.

The Commonwealth War Graves Commission maintains overseas graves, including cemeteries with Commonwealth dead. Clarke recalls using its grave-location app during a visit to Narvik. Both participants understand the Unknown Warrior's identity to have been deliberately left unresolved, without presenting a documented investigation. Anonymity allows the grave to represent many families' losses. Identification would change that commemorative role. Repatriation is contrasted with British burial near where people fell.
