Former Zambian President Edgar Lungu has accused government of persecuting him, after his wife was summoned for interrogation.

Esther Lungu is wanted for questioning by the Drug Enforcement Commission in connection with 15 flats she owns in Lusaka.

The commission alleges that the properties may have been dubiously acquired, which she denies.

Addressing lawmakers for the former governing party, the Patriotic Front, who went to see him and his wife in show of solidarity, Lungu said his family was being unfairly targeted.

Several former government officials have been appearing for interrogation with some of their property seized as part of the new government’s fight against corruption.

Lungu’s party last year lost power to incumbent Hakainde Hichilema of the United Party for National Development.
