Maybe some of our fellow British noders can correct me but I believe this oath, written in 1689, is still in use today when a new King and Queen are (what we would call in the states) sworn in.
Coronation Oath of 1689
Whereas by the law
usage of this Realm
, the King
s and Queen
s thereof have taken a solemn oath upon the Evangelist
s at their respective coronations, to maintain the statute
s, laws, and customs
of the said Realm, and all the people
and inhabitants thereof, in their spiritual
and civil rights
and properties: but forasmuch as the oath
itself on such occasion administered, hath heretofore been framed in doubtful
words and expressions, with relation to ancient laws and constitutions at this time unknown: to the end therefore that one uniform oath may be in all times to come taken by the Kings and Queens of this Realm, and to them respectively administered at the times of their and every of their coronation
