Former New York state Senate Majority Leader Pedro Espada was dealt a major setback in court yesterday — and now says he may abandon his controversial request for a new trial.

Just days ago, Espada announced he’d seek a new trial because of alleged missteps involving a jury that last year convicted him of embezzlement charges.

The development came minutes after Brooklyn federal Judge Frederic Block rejected Espada’s pleas to hire a new attorney and postpone his June 14 sentencing on embezzlement and tax-fraud charges.

Espada said he’s worried his challenge would break his tax-fraud plea deal. With the agreement, he’s looking at five to seven years, but faces a longer sentence if he breaks the deal by failing to acknowledge wrongdoing.

“I’m going to be meeting with my family this weekend — and whatever they decide, I will do,” Espada told The Post after the hearing.
