Nassau County Executive Laura Curran’s husband resigned Friday from his recently appointed position with the MTA amid conflict of interest concerns, The Post has learned.

John Curran was set to make as much as $240,000 annually doing legal work for the MTA’s Board of Directors, which his wife — Nassau County’s top leader, Executive Laura Curran — helps appoint.

In a resignation letter obtained by The Post, Curran insisted he could have been “very helpful” to the agency, but decided to “to prevent baseless assertions in the press from unnecessarily distracting” from its “important work.”

MTA rep Abbey Collins confirmed Curran’s departure.

“John is an extremely talented attorney. We respect the decision and wish him well,” Collins said in a statement.

Controversy dogged Curran’s hiring from the get-go.

One MTA board member told The Post the panel was not consulted before Curran was named to the lucrative post.

“I would have thought we would have been consulted,” said the MTA Board’s riders representative, Andrew Albert.

“We would have had a dark cloud having over any decision,” Albert said. “Questions would always be raised. The lawyer representing the MTA board shouldn’t have any questions or presumed questions raised about conflicts.”

Curran’s selection — first reported by Politico New York — outraged good government groups, who charged the selection reeked of nepotism.

Not only does Nassau County executive already have an appointee on the board, critics noted, but she’s also dependent on Gov. Andrew Cuomo — who controls the MTA — for county funding.

MTA Chairman Pat Foye attempted to defend Curran in the face of the furor.

“He’s extraordinarily qualified,” Foye said during a TV interview last week. “There was no board vote required for this. Had there been, the Nassau County representative would have abstained.”

That didn’t stop Nassau County Republicans from gearing up to attack Curran for hypocrisy over her husband’s hire — pointing out that she campaigned on an anti-corruption platform.

“After campaigning against patronage and nepotism, the county executive got caught doing exactly what she accused others of doing,” said Chris Boyle, a spokesman for the Nassau County legislature’s GOP majority.
