"He is one of the most experienced and senior leaders of the country. With his immense expertise, he will be able to provide guidance to the central government as well as the country," he said.
Gogoi said he and Mukherjee had been associated with each other for a long time.
"We did our best to help him in securing a resounding victory in the presidential polls and he has also appreciated our help," the Chief Minister said.
