Queen Letizia dealt another blow as bombshell book claims King Felipe was 'crushed and destroyed' by her 'infidelities'

Felipe's father Juan Carlos famously abdicated in 2014 following a series of scandals and affair rumours. Two years before, the ex-monarch's popularity nosedived when he was pictured posing next to a dead elephant in Botswana while Spain was struggling with the financial crisis.

In more recent months, Queen Letizia herself has been faced with unproven accusations of an affair with her ex-brother-in-law Jaime del Burgo.

Last month, Spanish journalist Jaime Peñafiel, 91, launched a fresh attack on the European Queen with his new book 'Letizia's Silences'.

Following his first best-selling book 'Letizia & I' (which alleged that Letizia had an affair with her ex brother-in-law Jamie del Burgo), the veteran royal reporter claims in his latest work that Felipe was 'aware' of his wife's alleged infidelity 'in real time'.

The author alleges that bodyguards joined Queen Letizia on a trip she took to New York in 2011 with her 'lover' Jaime del Burgo, whom she had dated before meeting Felipe.

The author wrote: 'That day [in New York], she was accompanied by her faithful escorts, who, without a doubt, any, they would pass a report to the Ministry of the Interior or [the Palace of] Zarzuela.'

Following this, Jaime claims that Felipe has been left 'crushed and destroyed' by his wife's alleged cheating.

The royal reporter - who worked for Hola! magazine for 20 years - claims that Felipe has been 'plunged into hell' by his wife's supposed 'betrayal' and 'wants to get out'.

Elsewhere in the book, Jamie labels Queen Letizia 'cold, emotionally immature and passive aggressive' and makes unsubstantiated claims she is 'hated' by King Felipe's family.

Jaime Peñafiel, 91, was sacked by the Spanish newspaper El Mundo after 20 years earlier this year following the publication of first book on the Queen called 'Letizia & I'.
