The UK has never had a Jewish Prime Minister.
Benjamin Disraeli was a British politician and writer, who twice served as Prime Minister under Queen Victoria (in 1868 and 1874-1880). He was a truly remarkable man. Disraeli played a central role in the creation of the modern Conservative Party, defining its policies and its broad outreach. Disraeli is remembered for his influential voice in world affairs, his political battles with the Liberal Party leader William Ewart Gladstone, and his one-nation conservatism or "Tory democracy". He made the Conservatives the party most identified with the glory and power of the British Empire. He is, at 2016, the only British Prime Minister of Jewish birth.
