The FIA has relaxed the ban on team radio messages following a meeting with team members in Singapore.

Last week, Charlie Whiting wrote to all the teams to inform them that the FIA would be dramatically reducing what a team is permitted to tell drivers via the strict enforcement of a regulation which states "The driver must drive the car alone and unaided". A list of prohibited and permitted messages was then released to clarify what teams could say via radio or pit board.

However, following a meeting with team members in Singapore, the FIA has delayed a ban on messages relating specifically to car performance until 2015 to allow teams more time to prepare for the change. As a result, only messages relating to driver performance will be prohibited from this weekend's Singapore Grand Prix onwards.
