Today, at about 5.30 this afternoon, Her Majesty The Queen became the longest reigning British monarch.
The Special Correspondent sent me the link about calculating the exact time when the current reign would break the previous record and which can be seen at http://www.macleans.ca/society/crown-calculus-the-math-behind-queen-victorias-record-reign/
The BBC News website has acomparison of the two longest reigns in Queen Elizabeth II: Elizabeth and Victoria in numbers
The Daily Telegraph has an illustrated account of the day's events which can be seen at Queen Elizabeth II becomes longest-reigning monarch on a day of characteristic modesty
Now I know Jacobites will, of course, cite the longer de jure reign of King James III and VIII from 1701 -1766. However Princess Philip of the Hellenes, as some Jacobites regard Queen Elizabeth II, will outstrip that in 2016 on May 21st if my rough calculation is right.
Long may she reign !
