The 'theoreticians' of the time said that the 'front' model of political organisation takes direction from a vanguard party, vaguely referred to at the Botswana National Front (BNF) as a 'core' group of sorts.
The reason, it becomes evident in retrospect, was for fear that forthright pronouncement of the leadership role of a vanguard party would have required the formation of such a party, which, if it was to oppose the Botswana Democratic Party (BDP), would have had to be socialist in its ideological world view.
