Princess Kate's surprise visit to National Marine Aquarium will feature on TV tonight

Kate will appear on the programme Secrets of the Aquarium this evening, despite her visit to Plymouth happening 17 months ago.

Still known as the Duchess of Cambridge at the time, Kate wore a pair of high-waisted shorts by Holland Cooper, a striped jumper by Erdem and her white Superga trainers.

The National Marine Aquarium took to Twitter with pictures of the princess getting stuck in activities with young people during her visit.

They captioned the post: "Join us TONIGHT for the FINAL episode of #SecretsoftheAquarium!

"There’s a surprise visit from the Princess of Wales, Xav meets his childhood hero, the new seahorse tank gets stuck in a door and Florence the shark has a pregnancy test!

"Tonight's episode will be on at 6.30pm."

One fan replied: "I can’t wait to see our Princess."

Another said: "What!! She was in my home town?"

Similarly, a royal watcher commented: "Looking forward to this."

"I've absolutely loved this series! I visited the aquarium for the first time just before it started, and am looking forward to a return trip in the new year," another fan added.
