It is one of the smallest parliaments in the world, for it only consists of 24 members. During the celebrations, newly introduced laws are proclaimed, accompanied by three ceremonial toasts to the Queen and the United Kingdom.
They mature at this time of year currants, therefore wine one of them is perfect for toasts.
