The high commissioner for Palestine was the highest ranking authority representing the United Kingdom in the mandated territories of Palestine, and the high commissioner for Transjordan was the highest ranking authority representing the United Kingdom in Transjordan. These posts were always held simultaneously by a single individual after the high commissioner for Transjordan was established in 1928.
The British representative to Amman was "responsible to the high commissioner in his role as representative of the mandatory power, but not in his capacity as head of the Palestine administration."
