君主/伊麗莎白二世（Elizabeth II）96歲
王儲/威爾斯親王查爾斯（Charles, The Prince of Wales）74歲

現存最古老的王室之一，是凝聚英國的重要象徵，並不具備實質政治權力。當前的英國王室是溫莎王朝，從1917年延續至今，目前在位的伊莉莎白二世是溫莎王朝第四任君主，已故配偶菲利普親王原是希臘王國王子，與女王結婚後放棄頭銜，成為英國王室成員。目前英國王室世系有血親關係者高達幾百萬人。
雖是象徵性元首，但英國王室的工作相當多。對內，女王必須主持國會開幕、御准議會法案、會見首相。對外，高階王室成員必須接待來訪外賓、拜訪海外國家、參加活動或典禮等。英國每年耗資上千萬英鎊維持王室的運作，所以國內也有廢除王室的聲音。目前大英國協有54個成員，其中有16個國家奉英國女王為自己的國家元首，構成全世界現存最大的共主邦聯（稱大英國協王國），總人口數達1.34億。

Monarch / Queen Elizabeth II, 96 years old

Heir / Charles, The Prince of Wales, 74 years old

Queen Elizabeth presides over one of the oldest monarchies still in existence and is an important figurehead for unifying the UK, but she has no real political power. The current British monarchy is ruled by the House of Windsor. Starting 1917, the reigning Elizabeth II is the fourth monarch of the House of Windsor. The deceased consort Prince Philip was originally the Prince of the Kingdom of Greece, but relinquished his title upon marriage to the Queen, and became a member of the British royal family. There are currently millions of people with bloodlines connected to the lineage of the British royal family. 

Although only a symbolic head of state, the British monarchy has quite a heavy workload. Domestically, the Queen must chair the opening of the congress, give her royal consent to parliamentary bills, and meet regularly with the Prime Minister. Internationally, the higher ranking royal family members must receive visiting foreign guests, visit foreign countries, and take part in events and ceremonies. The British royal family’s expenditures reach tens of millions of pounds per year, so there are people advocating abolishing the monarchy. There are currently 54 members in the British Commonwealth, among which, 16 countries accept the British Queen as their head of state, forming the largest personal union (known as the Commonwealth realm) still in existence in the world, with a combinedtotal population of about 134 million people.
