The high flying lawyer repping disgraced former JPMorgan banker Chirayu Rana in his salacious sex-slave lawsuit has suddenly dropped his client — just hours before a court hearing, The Post has learned.

Daniel Kaiser, who previously repped Jeffrey Epstein accusers, filed a consent to be “discharged” as attorney for Rana just hours before they were due to appear in court on Tuesday.

Shockingly, the document reveals that Rana does not have a new lawyer lined up, and will be representing himself “pro se” until he decides to find a new attorney.

The surprise filing comes ahead of an afternoon courtroom appearance, where he was supposed to argue for his client’s right to be officially known only as “John Doe” in the court docket.

Since the case was first filed, Kaiser has repeatedly defended Rana’s claims, even once stating that The Post would be “embarrassed” by its reporting on the scandal once all of the evidence is revealed.

Kaiser represented several Epstein accusers, including Jennifer Araoz, 38, a New York woman who said the deceased sex trafficker groomed her for sex when she was 14-years-old.

JPMorgan Chase executive Lorna Hajdini — who Rana claims turned him into a sex slave — has since filed defamation claims against him.

A JP Morgan spokesperson declined to comment on Rana’s latest legal headache, but reiterated that the firm has no intention of settling the matter, noting that the bank has maintained from the outset that the allegations are without merit.
