McLaren boss Zak Brown said that the coronavirus pandemic has plunged Formula One into "a very fragile state", warning that as many as four teams could even be driven out of business.
The 2020 world championship has been unable to start with eight races of a scheduled 22 already either scrapped or postponed.
"This is potentially devastating to teams, and if (it is devastating) to enough teams then it's very threatening to F1 as a whole," Brown told the BBC on the eve of a meeting planned to discuss cost-cutting in the sport.
