An accountant from Jersey could be 15th in line to the throne, if his parentage claims are proved.
Robert Brown from St Lawrence, Jersey, is renewing his legal battle to prove he's the illegitimate son of Princess Margaret, reported The Guardian.
The 57-year-old said he is willing to spend up to £100,000 fighting for legal documents relating to her will and to get practice direction papers about the sealing of royal wills drawn up at the time of Margaret's death in 2002.
Brown's previous high court appeal for disclosure of her will in 2006 and 2007 were dismissed by the court and labelled "imaginary and baseless". He is now fighting under freedom of information laws for the documents.
But Brown has refused to let the case lie, as he believes he was born to Margaret in 1955 and his father could be Robin Douglas Home, with whom she had an affair.
