Ally: DeB speech put me to . . . ZZZZZZZZZZZZZ

Insane how long Bill talked tonight. I love him more than ever but it’s awful. — Working Families Party head Bill Lipton critiquing Mayor de Blasio

That droning sound you hear is the mayor speaking.

One of Mayor de Blasio’s closest allies called his speeches “awful” because they go on for so long that people lose interest, e-mails obtained by The Post reveal.

Bill Lipton, state director of the lefty Working Families Party, e-mailed a City Hall staffer in late 2016 to deliver the harsh critique after enduring two sleep-inducing speeches within two months.

“Insane how long bill talked at somos tonight. I love him more than ever but it’s awful,” Lipton wrote on Nov. 12, 2016, referring to the annual Somos El Futuro political conference in Puerto Rico.

“Great stuff but he lost everyone [after] like 10 min and the… overall message got a little muddled.”

Lipton added that it was the “same as at our gala,” where de Blasio had spoken on Sept. 14, 2016.

Perhaps realizing that his comments might not go over well be- cause he was communicating with one of the mayor’s speechwriters at the time, Edward Lewine, Lipton concluded with, “Just FYI!!”

Lewine wrote back within minutes, “We’ll keep working on it.”

Lipton later said the observations had been “Offered with love!”

The speeches in question were delivered more than a year after de Blasio blasted his own speech- writers for providing him with dull material — communications previously reported by The Post.

“I’m really suffering because of underwhelming texts to work from,” the mayor groused to three top aides on March 10, 2015.

Other e-mails between Lipton and City Hall staffers — largely with then-intergovernmental aides Emma Wolfe and Michael DeLo- ach — show a symbiotic relationship between the administration and the Working Families Party.

The de Blasio administration took many of its policies on combating climate change straight from the WFP playbook, and relied on the group to “amplify” its message with supportive quotes and appearances at press conferences.

One of the most urgent asks from the administration came after de Blasio publicly called for a halt to protests against the killing of unarmed black men by police — days after two cops were assassinated in Brooklyn in December 2014.

“We really need you to push support for a ‘deep breath’, time to reflect and grieve. Mayor acknowledging that we have more reforms . . . but in respect to the families grieving, we all need to take a time out, come together as a city,” DeLoach wrote to Lipton on Dec. 22, 2014. “Statement, social media, etc. would be really helpful. Can we count on you to help?”

Lipton and City Hall declined to comment.
