The Scandal: Where Did Our Money Go? aired on and followed the Scottish business woman's rise and shocking fall from grace.
Despite her poverty-stricken childhood, Mone went on to become one Britain's most successful entrepreneurs after launching several businesses. The documentary showcased her journey to celebrity status before she went on to marry Douglas Alan Borrowman.
But in 2020, Mone and Barrowman became the centre of a huge scandal after becoming involved with PPE MedPro. During the Covid-19 pandemic, Mone used her personal contacts within the government to lobby for medical equipment contracts for the firm.
She repeatedly denied having any connection to the company, which was awarded UK Government contracts worth more than £200 million to supply personal protective equipment.
However, the couple finally admitted their involvement three years later, with Mone admitting her husband stood to gain £60 million profit from the deal. The documentary sparked outrage from viewers, with several demanding the Baroness serve jail time for using tax payers' money.
One wrote: "This Michelle Mone documentary is crazy. She fleeced the country and deserves to be locked up!" as a second agreed: "Don't you just want to see Michelle Mone go to prison."
Another fumed: "Michelle Mone needs jailed for treason. Absolute disgrace. How can someone steal so many millions and get away with it?"
Announcing they were switching off, a fourth said: "Going to have to stop watching this Michelle Mone documentary. I've already reached boiling point."
Michelle was appointed to the House of Lords in 2015 - an action that arguably led her to founding the PPE company and selling masks to the government for millions of pounds.
PPE MedPro was set up on May 12, 2020. The government subsequently bought £121 worth of surgical gowns and £80million worth of face masks from the company.
During the pandemic, Mone and Barrowman tied the knot in a lavish wedding ceremony before enjoying their honeymoon in the Maldives.
In an interview with Laura Kuenssberg, Mone continued to deny she did anything wrong.
"I don't honestly see there is a case to answer," she told the . "I can't see what we've done wrong."
Mone was supported in the documentary by her friend Dr Ted Anders, who said: "I know from conversations with Michelle and in her life that she doesn't want to hurt anyone. She doesn't want to treat anyone badly, she just wants to get to her goal.
"She's never deliberately trying to mislead. She is actually very sensitive. It hurts when the press goes at her."
The documentary also detailed Mone's friendship with Penny Lancaster, which came to an abrupt end when the underwear tycoon dropped her as the face of her lingerie company Ultimo.
Mone replaced her with Rod Stewart's ex-wife Rachel Hunter, prompting the Maggie May hitmaker to brand the entrepreneur "a manipulative cow".
"I don't think Penny has got a single bad bone in her body," he told The Sunday Mail at the time. "But Michelle's entire skeleton reeks of self-interest."
