Nobel laureate Amartya Sen has said all non-communal forces should come together for the 2019 Lok Sabha polls and the Left should not hesitate in joining them as "democracy is in danger".

"We must express our opposition to autocracy, we must fight against their autocratic trends, we must criticise the issues where we need to oppose the non-communal right wing forces, but we must not take back our hands when it comes to fighting communalism which is the biggest threat," he said.
