Racing Point driver Sergio Perez could race in the 70th Anniversary Grand Prix at Silverstone this weekend if he tests negative for coronavirus.
A Racing Point statement said Public Health England (PHE) had ruled he needed to isolate only for seven days.
This was the quarantine requirement when Perez first tested negative.
There had been confusion as to how long Perez would need to stay in isolation because the guidance in the UK changed overnight from seven to 10 days between his first and second tests.
Racing Point argued the first test, which governing body the FIA and F1 declared as “inconclusive”, was positive on the terms used by PHE. The FIA and F1 said he was positive only after his second test last Thursday.
This caused controversy within F1, with several senior figures feeling Racing Point should impose a 10-day isolation on Perez regardless of the technicalities of timing.
Perez is to be tested again for coronavirus on Thursday. If he is negative, he would be free to enter the paddock and potentially race.
