Blaz’s No. 2 leaving post

MAYOR de Blasio’s second-incommand is calling it quits.

First Deputy Mayor Anthony Shorris, a career bureaucrat tasked with keeping the city government running, will depart the administration as it heads into its second term, City Hall confirmed Wednesday.

Shorris, 60, came to City Hall with de Blasio in 2013 — and boasted a deep government résumé, with turns as finance commissioner and deputy budget director under Mayor Ed Koch, deputy schools chancellor under Mayor Michael Bloomberg and as executive director of the Port Authority.

At his appointment, de Blasio heaped praise, and responsibility, on Shorris (photo), saying he would head “day-to-day operations” and would “have my imprimatur to make sure our agenda is implemented each and every day.”

Shorris will likely be replaced by Budget Director Dean Fuleihan, an insider told the Daily News.
