The British Foreign Office, it is often remarked, has the task of looking after foreigners. In particular, the Foreign Office is so attentive to the interests of the Arab world that the public identifies British diplomats there as the Camel Corps. Previously British ambassador in Syria and in Iraq, Mr. Simon Collis is now the British ambassador in Saudi Arabia, where he has just confirmed his seniority in the Camel Corps with the announcement that he has become a Muslim. Moreover, he has just completed the Hajj, the annual pilgrimage to Mecca that a Muslim is obliged to make. A photograph shows him and Huda, the Syrian lady he married in 2011, dressed in the special white robes that Hajj pilgrims must wear as they process. On the embassy wall behind the smiling couple the official British coat of arms asks a question. What allegiance does he owe to the British monarch, and what to the Saudi monarch who sees himself Keeper of the Faith? If the Foreign Office is true to form, he should retire with a knighthood to add to his title of Hajji.
