Formula 1 has confirmed a 22-race schedule for the 2020 season, subject to confirmation from the FIA.
New races in Hanoi and Zandvoort will arrive in the first five races of the season, with Vietnam slotting between Bahrain and China and Netherlands coming before Spain as the first European race of the year.
Azerbaijan has moved to a later slot in the calendar between Monaco and Canada.
The calendar has been swollen to a record 22 races after the new events were added and races in Britain, Spain and Mexico were saved, with Italy expected to follow suit at Monza next week.
