The FIA have added another race to the 2013 Formula 1 calendar, although the identity of the grand prix has yet to be confirmed.
The 2013 calendar has been amended to make way for another European event with the German Grand Prix brought forward by one week to July 7.
That has freed up the weekend of July 21 for the likely return of the Turkish Grand Prix which was dropped after the 2011 season for financial reasons.
Istanbul Park is under new ownership and talks have been taking place in the hope of finding a way for it to be included in the calendar.
The change was confirmed following the final 2012 meeting of the World Motor Sport Council (WMSC) on Wednesday.
"The date for the 2013 Grand Prix of Germany has been moved to 7 July, and 21 July has been reserved for another F1 European event, subject to the approval of the relevant ASNs," the FIA confirmed.
It was hoped the French Grand Prix would return to the calendar in 2013 but an agreement has yet to be reached.
As well as the amendment to the calendar, the FIA also ratified a number of proposed changes to Formula 1 rules, including more stringent front wing deflection tests next season.
