A letter written by Juan Carlos to his Swiss lawyers in 2018 stated the gift was irrevocable, despite his having asked in 2014 for the return of the money. On 14 March 2020, The Telegraph reported that his son Felipe, King of Spain since 2014, appeared as second beneficiary (after Juan Carlos) of the Lucum Foundation, which had received a €65 million donation by King Abdullah of Saudi Arabia.
