Admitting that Modi is popular and especially among the business class, Sen after voting here in Bolpur at his birthplace, said though Modi has popular support he is not his favourite candidate at all.
"I would like someone secular," Sen said.
Sen said the leader guiding India should have a clear notion that the "expansion of economy requires a long term engagement with education and healthcare of the people".
He said only educated labour force can make the economy sustainable.
He said he voted because it is an important election and voting means recognizing the voice of the people. "Participating in the election is part of the political participation," he said.
He said he could not vote earlier owing to his academic engagements abroad.
He said if there is a possibility for a government by the National Democratic Alliance at the centre, then there is a possibility for other forces too.
