The Supreme Court will hear an appeal by imprisoned former MP Geoffrey Mwilima on Thursday.

The 68-year-old Mwilima has been in jail since August 1999, following his arrest in the wake of secessionist attacks that took place at Katima Mulilo in the then-Caprivi Region.

Late last year, the former lawmaker failed in his bid to get a High Court order for his release from prison.

Mwilima wants to be released on medical grounds, disclosing that he suffers from diabetes and kidney ailments.
