The Prince of Wales joked he has toasted the Duke and Duchess of Sussex's baby news "several times".

Charles was asked about becoming a grandfather again during a visit to Royal Lochnagar Distillery in Aberdeenshire.

After sampling a special 30-year-old malt, Charles was asked if he had toasted the news, to which he replied, laughing: "Oh yes, absolutely. Several times."

Charles, who has the title of Duke of Rothesay in Scotland, previously visited the Crathie distillery to commemorate the 140th anniversary of the first royal visit by Queen Victoria and Prince Albert in 1848.

To mark the occasion, a special cask of single malt whisky was laid down for Charles in 1988.

Returning to the Diageo-owned distillery on Tuesday, he unveiled a plaque and met with employees - including one who worked at Lochnagar when his cask was filled - before tasting the whisky.

The cask, presented as a gift, will be bottled on his 70th birthday next month and sold in aid of his charity.

The Prince's Foundation has already announced its intention to invest the proceeds in projects that will provide employment and training opportunities for local people, as well as attracting visitors to the area.

Diageo director Ewan Andrew said: "We are delighted to have welcomed His Royal Highness and to formally hand over this special cask, which will become the oldest single cask bottling of Royal Lochnagar Scotch whisky.

"We are particularly pleased that this will support the local community in Royal Deeside, which is so important to Royal Lochnagar and our people who live and work here."

During his visit, The Duke of Rothesay was invited to fill and sign a new cask that will now be laid down and matured at the distillery for future charitable activity.
