Motor racing's governing body announced in May that it wanted expressions of interest from teams that were eager to join the F1 field in either 2016 or 2017.

It said at the time: "Having due regard for the sustainability and future success of the Formula 1 world championship, the FIA has opened a new selection process to identify a candidate team to participate in the championship from the start of the 2016 or the 2017 season.

"The overall long-term interests of the championship will determine which candidate is selected."

Original June deadline

The FIA initially stated that the criteria for selecting those teams interested would be given to all those who had expressed an interest by June 30.

However, Motorsport.com has learned that this deadline has now been pushed back to July 23.

No reason for the delay has been given, but it could have been to give some teams considering applying more time to decide if they definitely wanted to do it or not.

The FIA hopes to be able to confirm which team, if any, it believes should be granted a place on the grid on September 30.
