Brussels Summit
The Brussels Summit is a summit meeting of the deputy leaders of the three member states of the Hanoverian Union, namely the United Kingdom, the Netherlands, and Luxembourg. Held at the Royal Palace of Brussels, which also serves as the official residence of the President of the Hanoverian Union, the summit meetings are normally held to discuss and subsequently lay out a new agenda for the organisation every five years. Therefore, each summmit meetings are considered to be a renewal of the organisation's "year" whereby a "year" constitutes a total period of five years during which the deputy leaders from each three member states take turns holding the chairmanship of the organisation for five years each.
The summit meetings are normally chaired by the President of the Hanoverian Union, whom is always the reigning monarch of all three countries. For instance, King Frederick, the organisation's first and founding president, chaired the organisation's inaugural meeting in 1946 while subsequent editions have been chaired by his successors Charles III and Thomas. The most recent, currently the sixteenth iteration, was held on 6 December 2021 and was chaired by Queen Alexandra.
