According to Debrett's, although known as Prince Radziwià Âà  in Britain, on becoming a British subject and in keeping with standard practice, Radziwià Âà  strictly needed permission from Queen Elizabeth II to use his princely title. The Radziwià Âà  family held the title Prince of the Holy Roman Empire since the early 16th century. However, noble titles were abolished in Poland and Austria.
