According to the author McNish, Parker's Presidency was at first only a galvanised iron building in the veld but later a more substantial place in the main street of Klipdrift was used. He writes, "A flag was designed showing "the Union Jack in the top right hand corner with a large rearing horse as the central item". This flag was hoisted daily on a flagstaff in front of the Presidency building.

When one considers that the majority of the diamond diggers were British subjects (from Natal and the Cape) and that the Union Jack and British Ensigns were widely flown on the diggings and the fact that the flag described by Theodore Doms contained a Union Jack, it is well within the bounds of possibility that the Red Ensign could have formed the basis of this flag of the Diggers' Republic.
