Congress MP Sonia Gandhi's long-awaited memoir, "Belonging: A Journey of Love", hit the stands on Tuesday, offering an account on why she turned down her party's offer to become prime minister and chose Manmohan Singh instead to lead the country in 2004. She said that she picked up Singh, the two-time prime minister who died at the age of 92 in 2024, as she thought of him as a person of "unquestionable".
