Duke of Edinburgh stops at Little Chef roadside cafe 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.
