Martin Brundle and Jenson Button voiced their disapproval after Charles Leclerc violated a gentleman's "agreement" which exists between Formula 1 racers.
The incident occurred during qualifying for the Monaco Grand Prix. The tight nature of the short street track means traffic is inevitable in those sessions, but Leclerc was guilty of blatantly getting in the way of Lando Norris as the McLaren racer attempted a hot lap.
Norris had to brake sharply to avoid slamming into the back of the Ferrari at high speed in the tunnel section of the track. Replays showed Leclerc was being told about a Max Verstappen lap over the radio at the time, rather than being warned about the approaching Brit.
