12-year-old on track to become racing legend

12-year-old Jack Miller's dreams are coming true.

The Northern Irish karting driver from Lisburn has returned home after a massive win in Spain.

He is now the Tillotson T4 Mini World Champion, but for Jack this is just the beginning.

"I want to become a GT3 world champion while I'm still young," he told BBC News.

The T4 Series is an international racing championship for small engine karts.

Karts - also known as go-karts - are small vehicles which young drivers can use to learn how to drive and race.

Many drivers, like Jack, hope to become professional motorsport racers one day.

Karting is also where some big name racers, like Formula 1 drivers Lewis Hamilton and Lando Norris, got their start.

But Jack isn't interested in chasing the same dream.

"I want karting to lead me to the GT3," he explained.

GT3 is different to Formula 1 (F1).

Drivers race sports cars that are legal to drive on roads instead of purpose-built racing cars like the ones used in F1.

Supporting Jack in Spain were his parents: "Our hearts were in our mouths," said Jack's mum Elaine. "My hands were shaking."

But she said Jack earned his place at the top of the podium: "Jack worked his way to the front and pulled away, kept his head down, managed not to make any mistakes and got across the line first."

And forget winning the trophy, an extra-tricky part was getting it back home to Lisburn!

The family were not allowed to take it on as hand luggage.

"I had to take everything out of all the suitcases and managed to get it into the biggest case and just wrap it in all the clothes," laughed Elaine.

"And then we were way over the weight, so we had to pay extra."
