"We are as agile as ever because we sincerely and honestly governed (the state)," Soren said after handing his resignation letter to Governor Syed Ahmed.
"Now I have handed over the resignation to the Governor," he said.
Without elaborating much, Soren said on one side it was the whole country and on the other side a small party JMM, of the poor, which gallantly fought.
On whether he thought a prepoll alliance with Congress would have been useful, Soren said he was not interested in "digging graves", but "we should learn from our mistakes".
