The Egyptian pharaoh queen Nefertiti could be buried in two newly-discovered rooms in King Tutankhamun's tomb, according to a British archaeologist.

Nicholas Reeves said on Egyptian TV that two extra rooms had been found hidden in the walls of the tomb.

Egyptian officials say they hope to give the go-ahead to use radar scans to test Mr Reeves' theory that Nefertiti's remains are hidden in one of them.
