Oliver has been Chief Executive and Keeper since March 2010, and over the past three and a half years has made a major contribution to the continuing success of the organisation.
Oliver said to staff, "While I'm greatly looking forward to the new opportunity with DVLA, it's been a privilege working with such a talented group of staff, our enthusiastic readers, and the people who make our archive sector so vibrant. I will miss The National Archives but will leave confident that our public task working for the record is greatly strengthened. I am very proud of all the organisation has achieved over the past three years - we have transformed the Kew site physically and environmentally, implemented a complete refresh of our world-class digital services, and delivered unprecedented transparency with the 20-year-rule change to the public record, at the same time as delivering significant savings to the taxpayer."
An update on the process for recruiting a replacement will follow shortly.
