The Duchess of Cambridge has been retracing her grandmother's footsteps during a visit to Bletchley Park near Milton Keynes.
She was there to mark the completion of an £8m, year-long restoration project to create a visitor centre and new exhibitions.
The Duchess's grandmother, Valerie Glassborow, worked alongside the codebreakers in the 1940s.
