State Congress chief Ashok Chavan also said that NCP and Congress would support each other in the Zilla Parishads.
Sena won 84 seats while its estranged ally BJP won 82 in the elections to 227-member city corporation, BMC. Congress with 31 seats was a distant third.
With no party winning clear majority and BJP and Sena locked in a bitter wrangling during the poll campaign, uncertainty looms as to who would control the BMC.
He was speaking to media after chairing a party leaders' meeting to take a stock of election results.
NCP proposed cooperation for Zilla Parishad presidents' elections, he said, adding that Congress had agreed to it.
"We agreed to the proposal. In the Zilla Parishads where we have higher number the NCP will support us while in the places where their number is higher we will support them," he said.
