Officials sources said Singh allocated divisions like disaster management, human rights, border management, north-east and a few others to Rijiju.
The Minister of State for Home will be incharge of the day-to-day affairs of the divisions and report to the Home Minister directly.
Singh himself will handle crucial divisions like internal security, Left Wing Extremism, centre-state affairs, police modernisation and a few other divisions.
"It is requested that the distribution of work between the Hon'ble Ministers of State in your Ministry kindly be sent to this office at the earliest", Modi has said in a note sent to cabinet ministers.
