I strongly object to the reason to still with hold this document, it is over 80 years old. Thirty years is the standard, fifty the exception, more than 80 years is nonsense gerenotocracy and clearly a threat to the future, setting a terrible leadership example, further covering up for unaccountable government over-reach. This information is crucial to understanding the UK's history and contextual place in the world, and prejudices against the youth. This is a gerontocratic decision by old people who are scared of the youth discovering the truth of history, which the youth have a right to know in order to make decisions about the future.
