The events surrounding South Africa's self-imposed June 30 deadline for undocumented foreign nationals to leave the country represent one of the most extraordinary chapters of governance in post-apartheid Africa, but they should also inject fresh urgency into the continent's integration agenda, Gabby Asare Otchere-Darko has said. In a strongly-worded analysis, the Founder and Executive Chairman of the Africa Prosperity Network drew parallels with historical mass expulsions across the continent — including Ghana's Alien Compliance Order of 1969, Uganda's expulsion of Asians under Idi Amin in 1972, and Nigeria's "Ghana Must Go" exercise of 1983 — but argued that South Africa's current crisis is fundamentally different and potentially more disturbing.
