In December 1949 Segovia retracted his renunciation as coerced and claimed that he was the rightful claimant to Spain's crown. Relations between Don Juan and Franco continued to deteriorate and in 1952 the latter prevailed upon Segovia to send his elder son to Spain to be educated under his guidance. Reluctantly, Alfonso moved from Switzerland to Spain, initially to study law at Deusto University and, in 1955 to attend the elite "Centro de Estudios Universitarios" (CEU). By 1956 Franco was diverting sponsors of some civic events from Juan Carlos, who was also being educated in Spain under the "Caudillo's" supervision, to Alfonso. By 1964 Franco considered Juan Carlos his preferred candidate for the throne over his father, but also considered that if the latter deviated from obedience to Franco or loyalty to his "Movimiento Nacional", Alfonso was a suitable alternative. Alfonso's strongest supporter in Franco's government was Jose Solis, minister and secretary-general of the "Movimiento". Anticipating that Franco would soon offer to declare him Spain's next king rather than Don Juan, in June 1969 Juan Carlos warned his father that if he declined Franco's offer, Alfonso would be invited to accept the crown, nevertheless Don Juan refused to consent to being bypassed. Nonetheless on 12 July 1969 Franco offered to designate Juan Carlos king whenever he stepped down from power, and Juan Carlos accepted.
