It's not like The Guardian. to bring news to the public a day after The Independent. has. Conal Urquhart's very pro-Israel though so he must have been waiting for some Arab involvement in the scandal:
"Doubts about the artefacts emerged after Israeli police began to hear rumours of an Egyptian craftsman living in Israel who would boast of his part in the forgeries while drinking in Tel Aviv."
So it's Egypt's fault.
