LONDON, April 14 (Reuters) - Racing ⁠Bulls will bring upgrades to the Miami and Canadian Grands Prix in quick succession next ⁠month after the cancellation of Formula One races in the Middle East disrupted the ‌schedule.

The Red Bull-owned team's boss Alan Permane told reporters in a video call on Tuesday that the situation was a result of Miami becoming the fourth round of the season rather than the sixth.
