A remarkable race that featured three safety cars and several crashes, including clashes between team-mates, was won by Red Bull’s Daniel Ricciardo who started 10th on the grid.

The result was doubly bitter for Hamilton as he ended up finishing fifth, a place behind Ferrari’s Vettel, and losing ground in the championship despite dominating the race until his unusual problem.

A loose head restraint cost Lewis Hamilton victory in a chaotic and incident-packed Azerbaijan Grand Prix as Sebastian Vettel was penalised for driving into his title rival.
