Indicted Senate Majority Leader Dean Skelos has finally come to his senses and is expected to step down from his post after a powwow Monday with fellow Republicans, sources told The Post.

The Long Island Republican, indicted with his son last week on federal corruption charges, will hear out his colleagues before relinquishing the leadership post, but not before making a bid to help anoint his successor.

Skelos had floated the idea of giving up his Senate seat entirely in an attempt to get Republicans to leave him in charge or risk losing their razor-thin majority.

But he is more likely to step down from the rostrum only and have a say in picking his successor.

“Dean probably sees the handwriting on the wall at this time,” said an influential Republican senator with a vote on the matter.

That senator said it would be bad for Skelos’ “legacy” to bow out completely or let his colleagues take the gavel from him.

“He’s not going to embarrass himself like that,” the senator said.

Skelos’ day in Albany will start with an 11 a.m. Republican conference meeting before a 3 p.m. Senate session. Such meetings usually begin at 2 p.m., but Republicans are giving themselves extra time this time, a source said.

Among the topics will be Skelos’ successor. Sources said Skelos favors state Sen. John Flanagan, a Suffolk County Republican, but another candidate, John DeFrancisco, an upstate Republican, has more seniority.

A source said Flanagan and DeFrancisco were going to meet Sunday night ahead of the morning conference meeting.

“It could go either way,” a source said. “Things are really up for grabs.”

The selection will likely be made before the meeting ends to avoid a public civil war.

“The Republican conference has to come out 100 percent united to elect the next majority leader,” said O’Brien Murray, a GOP consultant with ties to the Senate. “We could lose the majority.”

If that happens, Republicans may end up turning to state Sen. Simcha Felder, a conservative Democrat allied with Republicans.

Felder, of Brooklyn, insisted he was noncommittal.

“The Republican Party doesn’t own me. The Democratic Party doesn’t own me,” he said. “It’s not about the Democratic or Republican Party. It’s about success for my constituents.”

“I have to answer to God, my wife and my constituents. I don’t answer to the Republican Party or Democratic Party.”
