Prince Charles looked in great spirits today as he continued his visit to Scotland with a visit to a fish market in Lerwick.  

The Duke of Rothesay, as he's known in Scotland, dressed the part for the visit as he donned a kilt and sporran. 

Charles, 71, was in the area to officially open Lerwick Harbour Fish Market at Shetland Seafood Auctions Ltd on the second day of a two-day visit to Scotland.

He's expected to join his mother the Queen at Balmoral at some point in the coming weeks, with Her Majesty spending her first summer holiday at the Scottish estate since the death of her husband Prince Philip in April.  

During today's visit, Charles was shown fish landings at the new market, toured the facilities and visited the auction hall, where he met with fishing industry representatives.

Lerwick Port Authority chairman George Anderson said: 'It is a great honour to host The Duke of Rothesay's visit to open both markets. 

The visit coincides with the anniversary of the first landings and marks what has been a successful, if challenging, first year due to Covid.

'The construction of the Lerwick fish market was the climax of a lengthy, coordinated programme of projects, involving dredging and building quays, designed to future-proof the market’s role in helping to sustain and develop the fishing industry’s contribution to the Shetland economy.'

Prince Charles will later visit Lerwick Town Hall and the NAFC Marine Centre.

Yesterday, the royal met with volunteers cleaning up Scrabster Beach in Caithness.

After the event, Charles could be seen chatting with singer Katherine Jenkins, 40, who sang during the service and appeared totally charmed by the royal.

The pair, who first met over a decade ago, could be seen sharing a laugh with one another, with the Welsh singer appearing particularly tickled by a joke Charles had told.

The visit comes on the week Charles would have celebrated his 40th wedding anniversary with Princess Diana. 

However, the couple divorced in 1996 and Diana tragically died a year later on August 31, 1997 at the age of 36, after being involved in a fatal car accident in Paris. 

This week, declassified documents have revealed new details of the first official visit the pair made to Australia, soon after they married.  

The couple reportedly showed ‘great charm and tact’ on their first official trip in 1983 - including the moment Princess Diana ‘defused’ what could've been a 'slightly embarrassing incident' when a Republican protester tried to hand her a ‘Eureka’ flag during a visit to the new Parliament House in Australia's capital, Canberra.

However, as reported by the Metro, another 'confidential' document, written by the then New Zealand High Commissioner Sir Richard Stratton, to the Foreign and Commonwealth Office, highlighted a more unusual occurrence.

It reads: ‘The professional, mainly white, protesters made little impact. A well-known Maori agitator presented his bare – and hideous! – bottom (allegedly the worst Maori insult, but I have my doubts!) to Their Royal Highnesses as they drove into Wellington from the airport.’
