Fifty-four people will appear in a Zambian court on Friday accused of treason. They say the government has failed to honour one of the country's founding documents.
They're referring to a 1964 treaty with the Barotse monarchy, which had a strong influence over a large part of what is now Zambia. The area became the Western Province after the king signed the Barotseland Agreement, joining the rest of the region in the new independent Zambia.
Tania Page reports from the provincial capital of Mongu, where there are many who say the treaty's promise of autonomy was never honoured.
