New Delhi: Kripashankar Singh, Mumbai Pradesh Congress Chief, has resigned from the post in the wake of party's poor showing in the civic elections last week.

"Kripashankar Singh sent his resignation on the day the results of the election to Brihan Mumbai Corporation were out. It has been accepted," Mohan Prakash, Congress leader in charge of Maharashtra, told reporters on Wednesday.

The announcement of the resignation came on a day the Bombay High Court asked the Mumbai Police to seek sanction for prosecution of Singh under the Prevention of Corruption Act on a PIL against him on allegations of amassing income disproportionate to income.

The Shiv Sena-BJP alliance won the BMC elections to retain power for the third time defeating the Congress-NCP alliance.
