India is on the move. The economy is booming, transforming society and politics.
But in this new India is there room for a party that still clings to Marxist ideology?
The Communist Party of India (Marxist) are part of the government coalition - uneasy bedfellows with the Congress party.

Stephen Sackur asks Brinda Karat what it would take for her party to walk away from the coalition and bring down the government?
