New Delhi: In a move aimed at party's organisational revamp and electoral comeback, Congress president Sonia Gandhi has written to party chiefs in states seeking their opinion on ways to increase accountability and expand their base.

The move comes against the backdrop of demands to give "full responsibility" of the party to its vice president Rahul Gandhi, and the letter, sent last month but made available to the media Saturday, refers to his role in finalising the party's blueprint for the future.
