The Duke of Edinburgh surprised diners at a Little Chef when he stopped off at one of the roadside cafes in Yorkshire.
Philip called at the Doncaster Little Chef, which is on the A1, just north of the South Yorkshire town.
A spokeswoman for the chain said the Duke’s entourage only bought coffee during the short stop but she joked that he might be tempted next time by the £10.99 royal breakfast - Little Chef’s standard Olympic breakfast topped off with a sirloin steak.
The 93-year-old spent about 15 minutes at the roadside restaurant, which is next to a petrol station on the busy dual carriageway.
According to reports, he stopped off en route to a private engagement - a carriage-driving event in Cumbria.
This is not the first time the Doncaster Little Chef has hit the headlines.
In 1991, then prime minister John Major famously stopped for a fry-up at the cafe - which was then branded as a Happy Eater - on his way to the Young Conservatives’ conference in Scarborough.
