London - Formula One has decided to defer until the end of October its final presentation of the sporting regulations for 2021 after a meeting in Paris on Thursday that was also attended by world champion Lewis Hamilton.
The rules were due to have been put forward for approval this month but some teams pushed to extend the deadline because they felt there was still work to do on the technical and sporting side.
Formula One had originally wanted an October date but, without apparent unanimity, would have otherwise had to present the rules at a World Motor Sport Council meeting on Friday.
The governing FIA said the 10 teams had unanimously agreed to the extension.
The meeting was attended by all team principals and technical directors, the governing body, Formula One management, tyre supplier Pirelli and drivers Hamilton, Nico Hulkenberg and ex-racer Alexander Wurz.
