A book to be published in Hong Kong in the new year says Zhou Enlai, Communist China’s much-respected first premier, was probably gay despite his long marriage, and had once been in love with a male schoolmate two years his junior.

It is a contention certain to be controversial in China, where the Communist Party likes to maintain its top leaders are more or less morally irreproachable and where homosexuality is frowned upon, though no longer officially repressed.

The Hong Kong-based author, Tsoi Wing-mui, is a former editor at a liberal political magazine there who has written about gay-themed subjects before though this is her first book.

She re-read already publicly available letters and diaries Zhou and his wife, Deng Yingchao, wrote, including ones that detailed Zhou’s fondness for a schoolmate and emotional detachment from his wife, to conclude that Zhou was probably gay.

Zhou was premier from the revolution in October 1949 that brought the Communist Party to power until his death from cancer in 1976, a few months before the death of his revolutionary colleague Mao Zedong, the founder of modern China.

Reuters obtained excerpts of the Chinese-language book, called “The Secret Emotional Life of Zhou Enlai.” It is published by the same house that put out the secret diaries of former Communist Party chief Zhao Ziyang, who was ousted after 1989’s Tiananmen Square crackdown on pro-democracy demonstrators.

Tsoi re-read books published by the party in 1998 to mark the 100th anniversary of Zhou’s birth that contained public essays and speeches by Zhou as well as his diary, letters, poems, novels and thesis from 1912 to 1924.
