Swiss authorities began investigating Juan Carlos in March 2020 in relation to a $100 million donation given to Sayn-Wittgenstein in 2012. This donation was linked to alleged kick-back fees from Saudi Arabia. Sayn-Wittgenstein reportedly told the head Swiss prosecutor on 19 December 2018 that Juan Carlos had gifted her €65 million out of "gratitude and love", to guarantee her future and her children's, because "he still had hopes to win her back". A letter written by Juan Carlos to his Swiss lawyers in 2018 stated the gift was irrevocable, despite 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, the entity on the receiving end of a €65 million donation by Abdullah bin Abdulaziz, King of Saudi Arabia. On 15 March 2020, the Royal Household issued a statement declaring that Felipe VI would renounce any inheritance from his father. Additionally, the statement announced that the former king would lose his public stipend from the State's General Budget.
