Describing Congress leader Digvijay Singh as a mild and sober politician, Bihar chief minister Nitish Kumar has said Singh's recent statements have become a subject of research for him.
"I am of the view that Digvijay Singh is a mild and sober politician... but lately Singh has started giving statements which are quite explosive in nature," Kumar told reporters onboard a cruise liner while exchanging greetings with devotees on the occasion of Chhath last evening.
Kumar wondered whether Congress was taking Singh's outbursts "seriously".
"Digvijay Singh's recent statements and why he is making such statements have become a subject of research for me," he said.
He was reacting to Singh's statement a couple of days ago in Delhi that Nitish Kumar was "secular" but he was "in bad company (BJP) at present."
