Formula 1 legend and big sporting name Alan Jones has died at the age of 80, reportedly after suffering a brief illness.

Nine reports that Jones was diagnosed with cancer only weeks ago. He celebrated his 80th birthday on Monday.

Jones was one of only two Australians to have won the Formula One motor racing world championships — motorsport’s biggest prize.  The other was Sir Jack Brabham.

Jones also won a remarkable 12 grand prix titles across his F1 career.

He was described by F1 writer Gerald Donaldson as a “straight-talking, iron-willed” driver who fought his way to the top.

“We are extremely saddened to announce the passing of our beloved Alan,” his second wife Amanda said in a statement.

“He will be dearly missed and fondly remembered by those closest to him, as well as the many fans whose support he was always grateful for.

“Alan dedicated his life to motorsport, building a legacy that will live on through the countless people he touched along the way.”

“Through his achievements, passion and unmistakable character, both on and off the track, Alan left an enduring mark on the sport both nationally and across the globe.

“As a family, we would like to take this opportunity to thank everyone who was part of Alan’s journey for the many years of friendship, love and support.

“He was incredibly fortunate to have so many wonderful people around him.”

Jones’s career as a racing driver spanned from 1975 to 1986.

His first F1 victory was in 1977 at the Austrian Grand Prix at Osterreichring.

Alan then began a highly successful four-year stint with the Williams Ford team, winning four grand prix races in 1979.

In 1980, Jones won races in Argentina, Great Britain, Canada and the United States, making him the world champion.

He was the last Australian to be crowned an F1 world champion.

His motorsport career also featured two podium results at the Bathurst 1000.

Jones built a successful TV career as a motorsport commentator and was renowned for his straight-talking analysis.

He is a member of the Sport Australia Hall Of Fame and was made an MBE.

Jones and his father Stan are among only three father-sons to have won the Australian Grand Prix.

F1 Australian Grand Prix posted that Jones left an “extraordinary legacy” in Australian motorsport and world be deeply missed by the motorsport community around the world.

Jones was previously married to Beverley. He is survived by Amanda and six children — Christian, Amber, Zara, Jack, Camilla and Emma.
