Parts of the memoir are deeply personal.

Nicola Sturgeon says she may have appeared to be a confident and combative leader but underneath she is a “painfully shy” introvert who has “always struggled to believe in herself.”

She writes in detail about the “excruciating pain” and heartbreak of suffering a miscarriage after becoming pregnant at the age of 40.

“Later, what I would feel most guilty about were the days I had wished I wasn’t pregnant,” she says.

Sturgeon touches on the end of her marriage, saying “I love him” but the strain of the past couple of years was “impossible to bear.”

She also writes about her experience of the menopause, explaining that “one of my deepest anxieties was that I would suddenly forget my words midway through an answer” at First Minister’s Question Time.

“My heart would race whenever I was on my feet in the Chamber which was debilitating and stressful,” she says.

And she addresses “wild stories” about her having a torrid lesbian affair with a French diplomat by saying the rumours were rooted in homophobia.

“The nature of the insult was water off a duck’s back,” she writes.

“Long-term relationships with men have accounted for more than thirty years of my life, but I have never considered sexuality, my own included, to be binary. Moreover, sexual relationships should be private matters.”
