Nasser versus House of Saud

I was reading a beautiful speech by Nasser against House of Saud from 1963.  He referred to the title of Protector of the Two Holy Sites.  He said: he is not protector of the two holy sites.  He is the usurper of the two holy sites.  Nasser's senior aide, Sami Sharaf, told me that it was around that time that Nasser assigned him to be in charge of the overthrow of the House of Saud.
