Southampton University has published some of the personal diaries and letters belonging to Lord and Lady Mountbatten after a campaign by historian and literary agent Andrew Lownie, however others are still unavailable.
Lownie launched a crowdfunding campaign earlier this yer to gain access to the diaries, which are held by the university, after finding omissions while researching for his biography The Mountbattens: Their Lives and Loves (Bonnier Books UK). Southampton purchased the wider Broadlands archive from the Mountbatten family trust in 2011 and helped attract funding by stating it would "preserve the collection in its entirety for future generations to use and enjoy" and "ensure public access".
