Cremations in Greece

After a campaign lasting more than a decade - and despite Church opposition - Greek MPs have passed a law to allow cremations in Greece for those whose religion allows it. This may not include the Greek Orthodox Church which describes it as a violation of the human body.
lt is not known how far the new laws will go to helping alleviate the current fullness of Athens graveyards where a burial plot is only rented for three years before the body has to be exhumed to make way for the next coffin. This can be extremely distressing for relatives - in some cases the exhumed bodies have not fully decomposed. (So what happens next - or specifically, what happens to the exhumed bodies?)
