The place of Andrew Mountbatten-Windsor, former prince and brother of the king, in the line of succession to the British throne appears to be under threat in the United Kingdom.
Currently, Mountbatten-Windsor is eighth in line (after the families of princes William and Harry) to the Crowns of the United Kingdom and Australia. This makes it extremely unlikely he would ever become monarch, but his removal is more a symbolic act of repudiation.
Is it possible to remove him? The short answer is yes – but it would most likely be a time-consuming process involving many parliaments passing legislation.
