Konijeti Rosaiah (78), former Chief Minister of Andhra Pradesh, will be the next Governor of Tamil Nadu, succeeding Surjit Singh Barnala.
According to reliable official sources, the warrant for his appointment is likely to be issued by the Rashtrapati Bhavan on Friday.
The Congress veteran served as Chief Minister from September 3, 2009 to November 24, 2010.
He took over the reins amid unusual circumstances after the incumbent Chief Minister Y.S. Rajasekhara Reddy was killed in a helicopter crash.
A protege of the farmer leader and Swatantra party veteran Professor N.G. Ranga, Mr. Rosaiah has had a long political innings stretching over half a century.
He served in the Cabinets headed by M. Channa Reddy, T. Anjaiah, K. Vijayabhaskara Reddy, N. Janardhana Reddy and Rajasekhara Reddy in different spells between 1979 and 2009.
He handled virtually every important portfolio and presented the State budget for a record 16 times.
Mr. Rosaiah served a stint as Lok Sabha MP from the Narasaraopet constituency in 1998 and was president of the APCC in 1995.
He is now member of the Andhra Pradesh Legislative Council.
