The King received an unwanted memento from a visit to a seaside resort where he celebrated the work of local charities – a splattering from a seagull.
Charles joked about his encounter with the bird that left its mark on the bottom of his suit jacket as he toured the Northern Ireland town of Newcastle.
The King was about to start a meet and greet with the public that lined crash barriers along the main street when the bird’s droppings struck, hitting Charles and those around him including the press.
Irene Marting, 64 from the village of Dromara near Lisburn, was waiting in the crowds with her sister Paula Leitch to see the King and witnessed the incident unfold from across the street.
After sharing a joke with Charles about the moment she said: “We were talking to the King about the seagull and he said ‘it’s well it didn’t land on my head’.
“Somebody was trying to get him to put a coat on but he didn’t, being hit by a seagull it’s supposed to be good luck.
“We’re so thrilled he’s come to Northern Ireland to see us and it’s really nice to see him in Newcastle.”
Earlier the King hailed “amazing” foodbank volunteers when he packed boxes of groceries for those in need during his second day in Ulster.
Charles was given the task of filling two boxes with bread, vegetables, tinned goods and toiletries, when he met helpers from the Pantry Foodbank based in a church in Newcastle that supports about 52 families a month.
He was told by the Pantry’s chairman John O’Neill the items were for one individual and later while looking at boxes destined for a family he made the volunteers laugh when he touched a toilet roll and said “very important”.
Earlier the King received a “VIP” movie ticket when he joined passionate film fans who have been running a community cinema in Newcastle since 2009.
He was shown the controls of the attraction’s screen and met Derry Girls and Game Of Thrones actor Ian McElhinney, along with staff and supporters.
Meanwhile the Queen carried out a solo royal visit and joked she was “not quite the expert, but my husband is” while pouring a pint of Guinness in Royal Hillsborough.
At the Parson’s Nose pub and restaurant she was invited to help in pouring a pint of the black stuff after meeting staff and received a round of applause for her efforts.
The royal couple ended their day by hosting a garden party at Hillsborough Castle, the King’s official residence in Northern Ireland, and the Queen met soldiers and officers from The Rifles, the regiment she serves as Colonel-in-Chief.
She asked them about a recent four-month deployment to Iraq, where they trained local forces, and they thanked her for a gift of Highgrove tea and shortbread biscuits.
Captain Harry Lin, from C company, 2nd Battalion The Rifles, said afterwards: “It was a very generous gesture, we were there at Christmas time and we shared the shortbread with our American colleagues.
“The Americans were generous to us so we returned the favour. They didn’t know what shortbread was at first but they kept coming back for more.”
