The Turkish Grand Prix has been cancelled just two weeks after it was put on the Formula 1 calendar.
The Turkey leg was added to the F1 schedule on June 11-13 to replace the Canadian Grand Prix, which was cancelled because of travel restrictions in Canada.
But Turkey has been put on the UK's travel red list of high-risk countries.
Instead, the Styrian Grand Prix will run at the Red Bull Ring on 25-27 June.
That date was originally scheduled for the French Grand Prix, which has now been moved a week earlier to 18-20 June.
The move means there will now be races on three consecutive weekends;the French Grand Prix at Paul Ricard, followed by the Styrian Grand Prix and then the Austrian Grand Prix, both at the same track.
"We were all looking forward to racing in Turkey but the travel restrictions in place have meant we are not able to be there in June.
"F1 has shown again that it is able to react quickly to developments and find solutions and we are delighted that we will have a double header in Austria, meaning our season remains at 23 races,” F1 president Stefano Domenicali said.
F1 has a series of protocols aimed at minimising the risk of spreading Covid-19 and says it has conducted 17,000 tests this year with only 15 positive cases, a rate of 0.1%. It says it will "continue to operate in a way that protects the safety of our personnel and the communities we visit".
