Allegedly coke-addled, wife-swapping banker resigns

Sage Kelly, the investment banker whose estranged wife claimed he pushed her into sex swaps and binged on hard-core drugs, has quit his $7 million-a-year job at Jefferies.

Kelly’s colleagues learned about his departure in a company memo Wednesday.

“Given everything that’s happened this just isn’t the time for 70-hour weeks and constant travel,” a Kelly confidante told The Post.

“He’s really grateful for the understanding of his clients,” the pal said, adding the resignation was voluntary.

A Jefferies spokesman declined to comment.

The news hit a day after the Wall Street bank announced a $93 million loss in its fiscal fourth quarter.

During that period, the firm fended off bad press, including a sworn statement by Kelly’s estranged wife, Christina di Mauro, that the head of investment banking at Jefferies, Ben Lorello, was part of a group who used cocaine with Sage. Lorello denied the claims.

During his divorce, Sage was forced to take a leave of absence. He remained out of work after announcing a settlement with his ex in November.

The sleazy saga started when Sage allegedly planted cameras in his Fifth Avenue pad this past summer in a bid to get custody of his kids. But the plan backfired and Christina took revenge in court papers.

A Jefferies insider said the company just wants the Kelly drama in its rearview mirror.

Lorello and other employees named in the suit will keep their jobs, the source said.
