Reham Khan has broken her silence over the contents of her controversial upcoming autobiography in an interview with CNN-IBN yesterday.

Her interview, which was featured as part of the show Face Off, reveals that her book portrays her former husband, Pakistan Tehreek-i-Insaaf (PTI) chief Imran Khan, as two-faced and turning a blind eye to the sexual harassment and coercion that she says runs rampant in his party.

Reham refers to her biography as "an in-depth book about my life and relationships" and explains that "those relationships and their problems... have an impact on the futures of all Pakistanis and people in our region."

She elaborates about the book's contents, "So I've discussed morality in terms of nepotism, meritocracy or the lack of it, sexual harassment, sexual coercion and how sexual favours are used for political and media positions, and some of [those incidents] are directly related to PTI."

While she didn't name them, Reham insists that there are specific incidents of sexual misbehaviours mentioned in the book.

When asked if Imran Khan was directly involved in those issues, she said, "People at the top have to take responsibility for what happens in their household and in their party."

When asked again if women have reason to have apprehensions [of being sexually coerced] in relation to Imran Khan, Reham grew vague, "Yes. Why I've talked about it is that I feel that if one woman can compromise, another woman who deserves the position will lose their career."

Reham also touched on what she called Imran's shifting loyalties which she said was a disturbing trend that voters in the upcoming election needed to be aware of.

"When I voted in 2013 for Imran Khan, I didn't know what I was voting for," she says, adding that she won't be voting for PTI again.

"They haven't done anything in KP," she explains. "When you vote for someone who professes to be different, you have higher expectations. The fact is we have seen the same sort of politics or much less strength in addressing some issues."

"I wouldn't have a problem with someone promoting a certain religious agenda if they believed in it and equally I wouldn't have a problem with someone who's very pro-military because we'll know where they stand [...] But Imran's Islamist agenda is not really an Islamist agenda. It's an agenda that will secure votes. If you're using the right bank vote just to become Prime Minister, I have a problem with that."

She adds, "People have constantly referred to the fact that he's Mr U-turn. There's a line in the book where I say [to him when I was his wife], 'You know I won't be voting for you in the coming election' and he just laughs. [I said] I don't know what he's about."

"It's not only about Imran," she clarified. "[In my book] I traced what is this frame of mind we're in when we go in to vote, what is the information [we have] at hand. You expect journalists covering certain issues to know a little better. But I argue whether we really know what we're voting for."
