Formula One's ruling body, the FIA, has announced an additional race in Europe for the 2013 season.
The event venue is yet to be decided, but it will make up for a postponed Grand Prix in New Jersey.
The FIA World Motorsport Council moved the German Grand Prix forward by one week to July 7, and July 21 "has been reserved for another F1 European event, subject to the approval of the relevant ASNs [national bodies]", it said.
The German race will now come a week after the British Grand Prix. The FIA did not announce a venue because the planned site, the Nuerburgring, is in financial trouble and may not be able to stage the race. If that is the case, the German GP would be held at Hockenheim, as was the 2012 edition.
