The Department for Personnel and Training had forwarded to the Union Public Service Commission (UPSC) its approval for dismissal of the suspended officers, they said.
According to sources, the order for their dismissal is likely to be issued in a couple of days.
The state government had also sought permission for the prosecution of the couple and communication in this regard is also expected soon, they said.
Earlier this year, a special anti-corruption court had issued notices to the IAS couple and their relatives, for the confiscation of their properties said to be worth Rs 22 crore in total. The couple are facing charges under Prevention of Corruption Act.
Also, following Madhya Pradesh government's approval, the Lokayukta had filed an application in the special court, seeking consent for confiscation of the couple's properties on the ground that they were acquired through illegal means and were disproportionate to known sources of their income.
