Prince Charles was in grave danger during his investiture on July 1, 1969, as a Welsh nationalist plotted to attack the Royal Family. Royal biographer Richard Aldrich claimed Welsh nationalists planned to use kamikaze dogs to attack the royals but other members, who were dog lovers, put a stop to it. During the period leading up to the Investiture, many targets were bombed.

       Speaking to True Royalty's Royal Beat, Mr Aldrich said: "This is the investiture of the Prince of Wales in 1969.

       "One of the things we love when we were researching for the book, the reasons these plots fell apart was the Welsh nationalists were planning on using kamikaze dogs.

       "They got these dogs, they were going to fit them with explosives and send the dogs towards the Royal Family and of course some of the Welsh nationalists are dog lovers.

       "They actually blew the gaff on some of these plots."

       The revelation comes following Charles' trip to Scotland where the prince was caught adding a tot of whisky to his tea on a visit to a kilt shop in Aberdeenshire.

       The Duke was given the cuppa and dram at Gibbs - Gentlemen's Outfitter in Inverurie and decided to mix the two.

       The store, which sells designer brands and formal wear for hire, including kilts, hosted the royal visitor as he toured local shops and the town's farmers' market on Tuesday.

       Earlier, Charles met one of the stars of the BBC's series Trawlermen during a visit to Amity Fish Company Ltd in Peterhead.

       The company is headed by renowned skipper Jimmy Buchan, who starred in the Bafta award-winning series.

       Mr Buchan said: "We were proud to host a walk-through of our supply chain operations, where we explained our desire to improve on our sustainability footprint and how we are working to improve the integrity of our products during transit to customers."

       Charles also learned about the challenges to the business from Covid-19 and lockdown.

       Charles also visited Rora Dairy, which produces a range of Scottish yogurts on an organic family-run farm near Peterhead.

       Bruce and Jane Mackie welcomed him to their farm, which has been selected to supply November's Cop26 climate change conference in Glasgow.

       Mrs Mackie said: "This year has been tremendously exciting for us all at Rora and we were delighted to welcome Prince Charles to the farm to show him the results of our work to improve biodiversity and sustainability here.

       "Our organic certification and selection for Cop26 is recognition of our efforts and, like so many of our customers, we really feel that the prince, who is a farmer himself, understood and appreciated this."

       Glen Garioch in Oldmeldrum, one of the country's oldest distilleries, is also welcoming Charles during his royal tour of the north-east.
