In the meantime, more and more princes were passed over. In January 2015, Ibn Saud's last son, Muqrin, became Crown Prince, only to be ousted three months later in favour of his nephew, Mohammed bin Nayef. Mohammed bin Nayef, the first grandson of Ibn Saud to hold the title, was himself removed in June 2017, and replaced by another grandson of Ibn Saud, Mohammad bin Salman. The honorific title of "Deputy Crown Prince" only dates from 2014, but the position, under the title of "Second Deputy Prime Minister" goes back to 1967, in order to designate who was the senior prince not excluded from the throne. By late 1964, it became obvious to those at court that Crown Prince Mohammed was not suitable for the throne and that King Faisal wanted to also bypass the next three in line and install Prince Fahd to be his heir. However, a faction loyal to the soon-to-be-out crown prince wouldn't have it, so as a compromise, Prince Khalid, who was considered a nonentity, would be next in line; Princes Saad and Nasir, who had no qualifications aside from seniority, would be skipped as planned, and that Fahd would take the title of "Second Deputy Prime Minister" to cement his place as second in line. When King Faisal was assassinated in 1975, King Khalid designated Prince Abdullah, who was next in line anyway, as second deputy. As King Khalid became ill with old age, the question of who would succeed Abdullah as second deputy became more pressing. Prince Musa'id, whose son had murdered King Faisal, long knew he was out and Prince Bandar demanded and got, a huge bribe to stand down. Prince Sultan, despite opposition, was appointed when the old King died. Muqrin was the first one to hold deputy crown prince position in 2014. Since 21 June 2017, the post of deputy crown prince has been vacant. The Royal Standard of the Crown Prince consists of a green flag, with an Arabic inscription and a sword featured in white, and with the national emblem embroidered in Silver in the lower right canton. The script on the flag is written in the Thuluth script. It is the "shahada" or Islamic declaration of faith:
