The Duchess of Cambridge has visited the newly restored Bletchley Park where she will meet a codebreaker who worked with her grandmother.

The home of the Government Code and Cypher School in Buckinghamshire cost £8m to restore and was mostly funded by the Heritage Lottery Fund.

The duchess will officially open the restored centre later on Wednesday.

Her paternal grandmother, Valerie Glassborow, worked at Bletchley's Hut 16.
