The FIA has announced that the number 17 has been retired from Formula 1, following the death of Jules Bianchi.
Bianchi selected number 17 when the sport introduced driver numbers at the start of the 2014 campaign, prior to his ultimately fatal accident in Japan last October.
"As F1 car numbers are now personally chosen by each driver, the FIA believes it to be an appropriate gesture to retire Jules Bianchi’s number 17," read a statement.
"As a result, this number can no longer be used for a car competing in the FIA Formula One World Championship."
Bianchi's funeral will take place in his native Nice on Tuesday morning.
