It was the third round of the 2017 FIA Formula 2 Championship and was run in support of the 2017 Monaco Grand Prix.
After an aborted start due to Antonio Fuoco and Sean Gelael stalling on the grid, Charles Leclerc led into the first corner, followed by Alexander Albon and Oliver Rowland.
A concertina effect occurred at the Grand Hotel Hairpin as Canamasas was spun, causing Gelael to lose his front wing and bringing out a local yellow.
Whilst Leclerc was setting fastest laps up the front, Nicholas Latifi went out with engine failure in the tunnel, bringing out the safety car.
Leclerc took his compulsory pitstop immediately and came out in fourth place after initial confusion with the safety car saw him lose the gap and then some to Rowland.
