The Duchess of Cambridge has arrived at Bletchley Park to view a special exhibition marking the 75th anniversary of the D-Day landings.
Kate Middleton, dressed in a £1,750 Alessandra Rich navy blue and white polka dot dress, smiled and chatted to youngsters in the crowds as she arrived today.
She previously wore the classy frock in the official photographs marking the Prince of Wales' 70th birthday last year.
The historic Bletchley Park Teleprinter Building was where Codebreakers received hundreds of thousands of enemy messages, intercepted at secret listening posts across the UK, throughout the Second World War.
Kate Middleton's own grandmother was among the clever Codebreakers who deciphered Nazi secrets when the work going on behind the mansion's closed doors was one of Britain's most closely-guarded secrets.

The building will now host the special exhibition D-Day: Interception, Intelligence, Invasion.
The exhibition includes an immersive film, based on newly declassified material, which shows how the intelligence effort coordinated at Bletchley Park helped specifically in the success of the D-Day landings at Normandy.
Using sophisticated codebreaking techniques, workers at Bletchley Park fed crucial information to Allied forces in the critical months, weeks and days leading up to D-Day on 6th June 1944.

During the visit, Kate Middleton will meet with veteran codebreakers who worked at Bletchley alongside The Duchess’s own grandmother Valerie Glassborow, and her twin sister Mary, during the Second World War.
She will also view the interactive exhibition and meet with those who worked together to deliver the restoration of the building.
Kate will then meet schoolchildren taking part in one of Bletchley Park Trust’s learning activities.


An immersive workshop based on the new exhibition allows pupils to take on the role of codebreakers in June 1944, intercepting and deciphering German communications in order to understand their order of battle and decide whether the Operation Fortitude deception plans have been successful.
The Duchess of Cambridge visited Bletchley Park in 2014, following the restoration of the exhibition and heritage site.
