Mercedes suffered a qualifying disaster in Monaco after George Russell was forced into an early exit.
The Silver Arrows had already lost Kimi Antonelli earlier during the session for the Monaco Grand Prix when the Italian crashed at the end of Q1 coming out of the tunnel.
But Russell soon joined his team-mate in an official Q2 exit during qualifying at Monte Carlo, when he lost power earlier in a lap and cruised to a halt inside the tunnel, risking a crash, and thus bringing out a red flag to stop the session.
