"It was not an easy decision to make...to leave politics," Cheema said while addressing a presser, flanked by wife Musarrat Cheema.
"You serve the nation in politics, but not at the cost of the armed forces…not at the cost of people who protect the country," he maintained.
He further said that there were no plans of launching an attack; the workers were set to stage a protest and that’s all.
Cheema went on to add that Imran Khan and some other PTI leaders were to blame for the violence, as their narrative reached its peak on May 9.
Speaking on the occasion, Musarrat expressed remorse at the unrest, saying if she could, she would've erased the day from her life.
Earlier today, another PTI leader, former lawmaker Maleeka Bokhari announced to quit the party, shortly after her release from the Adiala Jail.

"Everyone may have their own reasons for leaving the party. As a patriot, I cannot stand with whatever happened [on May 9], that is why I am leaving PTI," she told media persons.
A day earlier, party stalwart Fawad Chaudhry announced to part ways with Imran Khan, and said he had resigned from the party position.
“Ref. My earlier statement where I unequivocally condemned 9th May incidents, I have decided to take a break from politics,” he said in a tweet.
“Therefore, I have resigned from party position and parting ways from Imran Khan,” he added.
Hours after Fawad's presser, senior leader Asad Umar announced to resign as PTI's secretary general.
"I have only resigned from the party position and the core committee," Umar said while addressing a presser following his release from Adiala Jail.
On Tuesday, senior leader Shireen Mazari announced to quit the party and “active politics”, a day after she was taken into custody from outside Adiala Jail after she was released on court orders in another case.
