Monaco: The Formula One drivers union on Saturday called for better safety measures on race circuits after the death of French driver Jules Bianchi. F1 must "never relent in improving safety," the Grand Prix Drivers Association (GPDA) said in a tribute to Bianchi who died nine months after suffering critical brain injuries in a crash at the Japanese GP.

The GPDA called Bianchi "a great talent, a great man and a great friend. Twenty-one years after the deaths of Ayrton Senna and Roland Ratzenberger, we have now lost Jules, who has died as a direct consequence of an on track accident.
