A five-time chief minister, Singh said the initial trends indicate that the Congress would form its government in the hill state.
Singh said there was no possibility of the Congress high command nominating an outsider for the chief minister's post.
"I can only say I don't expect this will happen," he had said yesterday when asked if a person from outside could lead the Congress government if the party comes to power.
Singh had on Wednesday also dismissed suggestions that Union minister Anand Sharma, his known detractor in state politics, stands a chance to become the chief minister.
"Whether he (Sharma) is a contender or not, I don't know, but he will not be there," he had said.
