Duke of Edinburgh quips as he receives honorary doctorate from Plymouth

The Duke of Edinburgh has received an honorary doctorate of marine science from Plymouth University in recognition of his decorated career in the Royal Navy.

Accepting his award Prince Philip joked about the length of his university career and how he approached it from a different direction from most, quipping:

The Duke also publicly unveiled the university's £19 million marine building, which contains state-of-the-art equipment used to train the next generation of mariners.

The visit comes during a year dogged by health scares for the royal. In August, he spent five nights in Aberdeen Royal Infirmary where he was treated for a recurrence of a bladder infection.

It came less than three months after he spent five nights in hospital with a bladder infection following the Diamond Jubilee Pageant on the River Thames.
