The future of the Mexican Grand Prix is in doubt after race organisers missed the deadline to secure their place on the 2020 calendar.
Mexico is one of five countries out of contract at the end of this campaign.
The Autódromo Hermanos Rodriguez’s hopes of securing a new deal were dealt a blow last month when the country’s president announced they would not continue to subsidise the event.
And although negotiations with Liberty Media continue, the organisers have revealed that they have missed the deadline to book their place on the 2020 calendar.
A statement issued by the Mexican organisers said: “After the deadline to keep the date that we were using for the Formula 1 Mexican GP expired, we would like to communicate that the promoters of the event had lost their preferred rights to keep that date in the 2020 calendar.
“Nevertheless, the negotiations either with F1 and the authorities of our country are still on course with the best spirit to find an alternative to keep the competition in Mexico.
“When we’ll have news about the negotiations we are maintaining with the authorities, we’ll make it public, only through official channels and spokespersons.”
As for five races being out of contract, F1 boss Chase Carey has played this down saying it is “nothing really unique”.
He told Wall Street analysts: “We have contracts where ’19 is the last year and we have either to create a new agreement or go our separate ways and there’s nothing really unique to this that wasn’t true last year.
“We had a number of renewals last year, just as we had a number of renewals the year before. There are different issues in each one.”
