PRINCE Louis has been heir-ing around Windsor in a toy electric car.

The five-year-old royal, whose excitable antics stole the show at grandad King Charles’s coronation, enjoys motoring in the vast gardens of the castle.

He has the run of 100 acres of private land on the estate, although he is supervised.

The ride-on toys, which can cost several hundreds of pounds, are loved by children up and down the country.

And an insider said of Louis: “He can use the paths that are running through Frogmore Gardens like a racetrack and it is completely private.

“The Queen used to use the area to go riding and take her dogs. Now Andy and Fergie go there with the corgis.

“It’s quiet and away from the public so ideal for Louis.”

It harks back to a previous snapshot of royal childsplay in 1952 — when three-year-old Charles was photographed in a pedal-car at Balmoral as his smiling mother, the late Queen Elizabeth, looked on.

This July, The Sun on Sunday revealed Louis’ dad William, 42, has an electric scooter to get from the family home on the estate to the castle for meetings or to see his father the King.

Wills’s eldest child George, now ten, used to ride a £100 toy tractor around his then Anmer Hall home near Sandringham.

But when he was four, he inherited from his father a miniature Aston Martin V8 Volante – one of only 25 of the British models ever built.

With a 160cc Honda engine, it had a maximum 20mph speed and boasted tan leather seats and green Wilton carpet.

The vintage car had been given to grandpa Charles in 1988, and he later gifted it to his son.

In happier times, warring brothers William and Harry also played together on a fire engine at Sandringham the same year.

Last year, The Sun revealed the late Queen had a souped-up electric golf cart to get around Windsor due to her mobility problems.
