The remains of general Wladyslaw Sikorski - Poland's World War Two Prime Minister and Supreme Armed Forces Commander - are returning to his crypt at Royal Wawel Cathedral after exhumation to determine the cause of his mysterious death in 1943.

Report by Slawek Szefs.

Officially, the air crash in which the general died had been reported as an accident and no details of the investigation then had been released. Perhaps new clues, if found, might break the long British silence on the Sikorski case, especially that what has been noticed by Polish examiners now differs considerably from British documents of over six decades ago.
