He said this practise eats into PSIP and DSIP funds which can be used for service delivery.
Marape said this when responding to Menyamya MP, Thomas Pelika.
Pelika raised concerns that Finance and Treasury officials in his District raised substantial claims that were eating into district funds.
He asked Marape to intervene and remove these officials.
The Finance Minister said he has heard of this practise and used the opportunity to sound a warning.
“Public servants must not be engaged in business,” he stated.
