Daniel Ricciardo claimed a shock win for Red Bull in a wild and controversial Azerbaijan Grand Prix which saw a major flashpoint between title rivals Lewis Hamilton and Sebastian Vettel.
In a race that was chaotic from the opening lap, when Valtteri Bottas and Kimi Raikkonen clashed while scrapping for second, Hamilton led through two Safety Car restarts and a full race restart following a red flag period. It was just before the Second Safety Car restart where the flashpoint occurred, with Vettel running into the back of Hamilton as he managed pace behind the Safety Car.
In a moment likely to become the most controversial of the season, an irate Vettel then pulled up alongside Hamilton and drove into the side of his title rival, something which later earned the championship leader a 10-second stop-go penalty.
