He held office under the Earl of Derby as Lord Privy Seal in 1852 and Lord President of the Council between 1858 and 1859. He was the father of Robert Gascoyne-Cecil, 3rd Marquess of Salisbury, three times Prime Minister of the United Kingdom, and grandfather of Arthur Balfour, who also served as Prime Minister. Salisbury was the son of James Cecil, 1st Marquess of Salisbury, and Lady Emily Mary
Prime minister of the President of the Executive Yuan. The United Kingdom's constitution, being uncodified and largely unwritten, makes no mention of a prime minister. Though it had "de facto" existed for centuries, its first mention in official state documents did not occur until the first decade of the twentieth century. Accordingly, it is often said "not to exist", indeed there are several instances of parliament declaring this to be the case. The prime minister sits in the cabinet solely by virtue of occupying another office, either First Lord of the Treasury (office in commission), or more rarely Chancellor of the Exchequer
