Prince Philip's affairs are protected by the UK government to claims royal experts as per Mirror.co.uk
Author Andrew Lownie says ministers have spent around £2million in blocking the archive left by Philip’s uncle Lord Mountbatten and his wife.
Dr Lownie to date has spent £460,000 in legal fees trying to find out what is mentioned in those 30,000 pages.
Dr Lownie said: “The only reason I can think of is that there is a reference to a lover of Prince Philip. The relationship between Lady Mountbatten and Nehru is well known.”
The Mountbatten family sold the papers to Southampton University in 2011 for £2.8million.
Dr Lownie, 60, took support from information laws to get access to the papers for his book.
