Prince William dons his navy uniform for the first time in 13 years and takes salute as he heads to Lord High Admiral's Divisions on behalf of King Charles

The Prince of Wales looked handsome as he stood to attention in his Navy uniform this afternoon during a visit to the Britannia Royal Naval College in Dartmouth.

Prince William, 41, donned the uniform for the first time in more than a decade, as he made the visit on behalf of King Charles. 

He appeared to be in high spirits despite the sensational Peter Morgan drama airing its latest episodes - which feature storylines about Prince Harry's Nazi costume scandal, a fictional meeting between Kate Middleton and Princess Diana and the late Queen having a very vivid dream about a 'King' Tony Blair - this morning. 

The royal made an appearance for a parade, which will see a total of 202 Royal Navy Cadets pass out with International Officer Cadets from Oman, Kuwait, Bangladesh and Trinidad & Tobago. 

William will also inspect the front rank of the Guard and the Royal Marines Band of Plymouth, as well as the ranks of St Vincent, Howe, and St George Division.

He is also set to meet with staff and cadets on the historic Quarter Deck.

This will include both those who took part in the parade as well as their instructors. 

The cadets have undergone 29 weeks of intensive training, which sees them train from civilians into junior naval officers.

They have been tested in a variety of scenarios: in the classroom, on Dartmoor, the River Dart, and at sea on board an operational warship. 

During his military career, William attended a training course at the Britannia Royal Naval College in 2008, following in the footsteps of his father, King Charles, and grandfather, the Duke of Edinburgh.

The father-of-three was all smiles during the event, sporting a navy uniform which consisted of a trench-coat with golden buttons, and a naval cap.

William also carried a sword.

It comes following The Crown's astonishing finale being released today, as Netflix unveiled the hit show's last six episodes this morning.

In one tense scene a young Prince William blames his father for Diana's death.

The first newly aired episode of the Peter Morgan show features a tense conversation between the father and son, when the now-Prince of Wales - played by Ed McVey - visits Windsor. 

Charles, who is portrayed by Dominic West, can be seen asking his eldest why he's 'angry with him', which the stubborn teenager initially denies - before admitting that his father 'never talks' about Diana.

'Why on earth would you think I wouldn't want that?' Charles questions.

'Perhaps because you don't like to be reminded how we got to this point,' William replies.

'Don't you think there might be a connection between where we all are now and your part in it?'

Charles appears aghast at the accusation, and says that his ex-wife's death was 'a terrible tragedy caused by one irresponsible man drinking too much and then getting behind the wheel of a car and driving too fast to escape from photographers'. 

'Which you and I both know she often encouraged,' he adds.

William then pushes on to stress that the fact that Diana was in Paris without any royal protection, which his father says was 'not his doing'.

The young prince then goes on to say that Diana 'should never have been anywhere near the Fayads'.

'She should have been safe with us and the fact that she wasn't - is your fault,' he continued.

'I know you didn't actually drive the car but you drove her into the arms of this that did - but making her so unhappy. By loving someone else.' 

The final six episodes of The Crown, which are released on Netflix today, will introduce actress Meg Bellamy as Kate Middleton alongside Ed McVey who plays William and Luther Ford as Prince Harry.

Pictures form the show, released earlier, show William and Kate sharing a heartfelt moment at university, while another depicts one of William and Harry's ski trips with their father, Prince Charles.

One scene, made all the more poignant due to their current estrangement, shows a young William and Harry having a drink and a laugh together.

Imelda Staunton, 67, who plays Queen Elizabeth II, can be seen waving to the crowds during her Golden Jubilee in 2002 in another scene.

Earlier this month, following the release of the first four episodes of series six, Netflix teased a clip of Meg Bellamy and Ed McVey recreating Prince William and Kate Middleton's first kiss at a university event, in the trailer for part two of the royal show.

The final instalment of the big-budget royal drama, which has drawn criticism for scenes depicting the run up to and aftermath of Princess Diana's death in Paris, will focus on the young royals.

Storylines include Prince William trying to integrate into life at Eton in the wake of his mother's death as the monarchy has to ride the wave of public opinion.
