De Blasio emails reveal his tardiness ticked off ex-diplomat

Mayor de Blasio’s chronic lateness has gotten him heckled and booed by the public — and it even ticked off the US ambassador to South Africa, a new batch of City Hall e-mails revealed Friday.

Then-diplomat Patrick Gaspard admonished a de Blasio aide when she asked him to delay a planned phone call with Hizzoner, the ­e-mails show.

“Should have been changed earlier. That sched was unrealistic — even if he had tendency to run on time,” Gaspard wrote Laura Santucci on Jan. 12, 2014.

Gaspard — who now works for billionaire George Soros’ Open Society Foundations — also chided de Blasio directly when he failed to set up a time for them to talk more than two years later.

“Never heard back about this wknd,” Gaspard wrote on April 11, 2016.

In response, de Blasio sheepishly blamed his partying at the annual Inner Circle show and charity benefit thrown by the City Hall press corps. “It was nonstop, and then I totally crashed because of the late night at the inner circle,” the mayor wrote back.

“I’m going to have [an aide named] prisca find a time that works. Prisca, pls work your magic so Patrick and I can talk.”

The embarrassing e-mails were among thousands the de Blasio administration released in a data dump shortly before the start of the Memorial Day weekend.

De Blasio had fought to keep the e-mails private by claiming they involved correspondence with political advisers he deemed “agents of the city,” but a judge ruled against him after The Post and NY1 filed suit to see them.

The administration has been releasing batches of e-mails since then.

The latest trove is riddled with redactions that black out discussions among de Blasio aides, including political consultant John Del Cecato, who created the famed campaign ad featuring de Blasio’s son, Dante.

But the censors somehow missed obscuring de Blasio’s government e-mail address, which is revealed as BCCD@cityhall.nyc.gov.

One e-mail shows de Blasio gushing over a Washington Post op-ed column about the “emergence of a populist reform agenda” within the Democratic Party by Katrina vanden Heuvel, editor and pubisher of The ­Nation, a liberal weekly magazine.

“Katrina, this is a great article. You have a special ability to see the whole playing field and to remind progressives of our own power. Well done! Best, Bill,” the mayor wrote on May 12, 2015.
