Monza may have taken another decisive step towards a new Formula 1 contract, according to multiple media reports in Italy.
Autosprint reveals that Andrea Dell'Orto, the president of the Italian circuit's operator Sias, has stepped down.
The report says that Dell'Orto had been at odds with F1 supremo Bernie Ecclestone, amid Monza's troubled negotiations to renew its race deal beyond 2016.
Dell'Orto's replacement is Pier (Peter) Lorenzo Zanchi, a former rally driver.
Sky Italia agreed that Dell'Orto's demise, and the appointment of an all-new board of directors, is an "important turning point" for Monza.
La Gazzetta dello Sport also reported: "This should be one more step in securing the signature of the F1 boss and the continuation of the grand prix at Monza."
Dell'Orto is quoted as saying: "For the renewal of the contract with FOM, I have done everything necessary to achieve this goal.
"I hope [my departure] does not create discontinuity in the current negotiations, in particular as regards the contribution of the [Lombardy] region to keep the grand prix at Monza."
This year's Italian Grand Prix is scheduled for September 4.
