Bharatiya Janata Party (BJP); in December 2016, he was appointed spokesperson for
Mumbai region.[1] Sinha was subsequently included in the national media team of BJP.[14]
Reviewing for The Hindu, Reshmi Kulkarni found Of Love and Politics to be a "more head-spinning than heady" political thriller with occasional splashes of romance.[7] Reviewing The Edge of Desire, Kulkarni found the work to be a one-time-read that suffered from the intense cramming of a multitude of political affairs.[18] Sayoni Aiyar for
News18.com deplored how Sinha's female lead character defined herself entirely by relationships with men in her life.[19]
Reviewing for The Deccan Chronicle, Omkar Sane panned Let The Reason be Love as an epitome of mediocrity and predictability.[20] Sinha's non-fiction book on childcare, Daddy (2015), was described in The New Indian Express as written for "new-generation fathers."[21]
