A memoir by President Donald Trump’s niece due to be published next week describes the president as a pathological narcissist who cheated on the SAT college entrance examination and has embraced “cheating as a way of life” ever since, according to US media outlets who received advance copies of the book.

The book by Mary Trump, the daughter of President Trump’s elder brother, describes how decades of dysfunction and relations with an abusive father moulded the man who would become president into a reckless leader who, according to publisher Simon & Schuster, “now threatens the world’s health, economic security and social fabric”.

The Trump family has been embroiled in a legal battle to halt publication of the book – titled “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man” – but an appellate court in the state of New York cleared it for release over the objections of Robert Trump, the president’s brother.

Robert Trump has said the book would violate a confidentiality agreement tied to the estate of his father Fred Trump Sr, who died in 1999. Mary Trump is Fred Trump’s granddaughter.
