Self-interest has to be sacrificed for the greater interest," Union Finance Minister Pranab Mukherjee told an election rally in presence of AICC President Sonia Gandhi.

The move came just a day after Mukherjee's warning that the rebels would face strong action, including expulsion, if they did not withdraw from the poll fray.
