The Turkish Grand Prix could once again be a fixture on the Formula One race calendar.
Turkish president Tayyip Erdogan and F1 CEO Chase Carey have reportedly "agreed in principle" over the Istanbul Park circuit's future, following a meeting on Tuesday that also included Vural Ak – the track's owner – and a handful of government representatives.
Following his installation as CEO in January, Carey has expressed a desire to strengthen the sport "in historic places like Europe".
ESPN reports that Ak believes Tuesday's meetings went well, with the circuit chief saying: "We had a meeting in Ankara with the President and Chase Carey from Liberty Media, whom I previously invited to Turkey personally before.
"All I can say at this point is that the meetings went really well and we agreed in principle. Although the contract hasn't been signed yet."
During its six-year stint on the F1 calendar from 2005 to 2011, Istanbul proved to be a popular fixture with fans, with the circuit's Turn 8 left-hander becoming infamous for being one of the sport's toughest corners. The track was dropped from the F1 calendar following the 2011 season, citing financial reasons.
The French Grand Prix will also make a return to the sport in 2018, following a decade-long absence.
