Former state Senate Majority Leader Dean Skelos and his son, Adam, fear that jurors will smell the “stink” of corruption if federal prosecutors get to play a secretly recorded conversation of their trash talk about Gov. Cuomo’s loved ones.

Defense lawyer Christopher Coniff argued on Monday that the feds were relying on “prejudicial innuendo that creates a taint or smear” to convict the father and son on influence-peddling charges.

“The introduction of all these little pieces is going to create a stink,” he said.

Those “little pieces” include the secret recording of a Feb. 27 phone conversation about the Cuomo family.

“I can’t stand this family. I really can’t stand this family,” Adam said, to which his dad replied, “Right.”

In the same conversation, the feds say, Dean discussed his plan “relating to disclosure of the outside income of the governor’s significant other,” Food Network host Sandra Lee.

Manhattan federal Judge Kimba Wood said the discussion was “relevant” but held off ruling on whether it could be played at the trial, which is set to start Monday.

But she ruled that jurors could hear testimony from workers at a medical-malpractice insurance company where prosecutors say Adam scored a no-show job through his dad.
