F1 rule changes approved

The nine 'refined' rules are designed to give drivers more control over their cars' electrical power management during races.

Four-time world champion Max Verstappen had previously hinted he might take a break from the sport if the technical issues were not resolved.

The changes were signed off during a meeting on Monday and will take effect ahead of the upcoming Miami Grand Prix.

Formula One management hopes the tweaks will appease the grid and ensure the competitive integrity of the current season.
