MILAN (Reuters) - The historic Monza circuit is to stay on the Formula One calendar after agreeing a new deal with the sport's organisers, Italian officials said on Wednesday (Aug 31).

The circuit near Milan has been on the calendar every year bar one since the championship started in 1950 but had no contract beyond this year and its future had been uncertain.

Mr Roberto Maroni, president of the Lombardy region, said on his Facebook that a deal had been reached.

"The Grand Prix will stay in Monza," he said. "With a few days to go until the signing of the contract, I'm very satisfied."

Cabinet under-secretary Luca Lotti, one of Prime Minister Matteo Renzi's closest aides, also said a deal had been done.

"Teamwork pays just as it does in Formula One," he said on Twitter.

Italian media said the new deal would be for three years.

Monza's absence from the calendar would be unthinkable for most fans, not least those of Ferrari for whom Monza is home territory.

This season's race will be held on Sunday.
