Formula One One bosses have unveiled a revamped calendar following the postponements of the Australian and Chinese Grands Prix.

The traditional curtain-raiser at Melbourne's Albert Park will move to 21 November, while the round in Shanghai, scheduled to take place on 11 April, will now only go ahead if another round drops off the schedule.

F1 officials have been forced into action with strict coronavirus travel restrictions in place in both countries.

The announcement means two of the opening three rounds have fallen by the wayside. But the sport remains confident of staging a record-breaking 23-round campaign.

Lewis Hamilton will kick off his championship defence in Bahrain on 28 March before the circus heads to Europe for a race in Imola on 18 April.

It is expected Portimao in Portugal will then host the third round on 2 May before the Spanish Grand Prix in Barcelona a week later.

Australia’s new date of 21 November means the season will be extended by one week, with the campaign closing in Abu Dhabi on 12 December.
