President John Mahama has warned deputy ministers against using the media to undermine their senior colleagues in government.

The president gave the warning when he swore in the last batch of deputy ministers at the flagstaff house.

He said such an attitude will not be tolerated by his administration.

“It is absolutely unacceptable to go on the media and cast aspersions against any of your colleagues or any of the ministers or any member of government.

“It is absolutely unacceptable,” Mr Mahama insisted.

He admonished the new deputy ministers to consult the office of the president should they have any cause for complaint.
