Brown has approached the High Court in
In a summons, he cites the Queen, the Attorney General and the executors of the wills of the Queen Mother and Princess Margaret as defendants.
Brown has also tried, unsuccessfully, to get information from the Department for Constitutional Affairs as well as the Prime Minister's and Cabinet Office.
Brown insists there is a public interest issue on the grounds of openness and consistency and says he would not object to the wills being made public, if they had once been made private to protect an illegitimate child.
Brown says he has been trying for four years to prove his parentage.
"I am not going to give up. I'm driven by a host of memories and a fundamental need to know.
"I have some evidence, including a photograph taken in October 1956 of a child sitting in a car in
Brown says there is some mystery surrounding his birth, with a Times announcement giving the date as
His parents are registered as Cynthia and Douglas Brown and Mr Brown claims Cynthia Brown had been a model working for Hardy Amies, who was a favoured designer of the princess.
He says years of research has led him to firmly believe the princess was forced to give up her "secret" son, but did visit him when he was young.
He claims there are other things to back up his claim, including a mystery Privy Council meeting on the day he was born.
He claims there were rumours of an illegitimate child in High Court circles with the closed wills of both the Queen Mother and Princess Margaret.
"The point is they've never, ever admitted or denied it", he said.
"This court summons is one avenue of many which is achievable, clean and clear cut, but win or lose, I won't give up."
It is unknown when the case will go before the High Court.
Brown claims the case raises the major constitutional issue of the rights of illegitimate children in the line of succession.
An illegitimate child cannot inherit the throne. The succession is governed by the Act of Settlement and the Royal Marriage Act, both of which are rather specific about who gets to be a dynast to the British throne.
Additionally, the media as a point of fact; should check and see what Princess Margaret was undertaking between December 1954 - June 1955; quite a lot in fact; including a tour of Caribbean, in February 1955. The Court Circular reports frequent public appointments for the Princess at this time. There are also various articles and photos of Princess Margaret for this time period, looking rather slim.
