It's the second time this year that Jean-Éric Vergne has been left without a seat at Toro Rosso, but this time it is for sure. The French driver had been ruled out of a 2015 driver with the Red Bull sister team after they announced Max Verstappen alongside Daniil Kvyat for next season. A spare seat became available when Kvyat was promoted to the Red Bull team, however, leaving some to speculate whether Vergne may have a second chance.

That pipe dream has come to an end now, with Vergne confirming that he won't continue with the Italian squad. After three years driving for the team, he tweeted that "I'll not drive any more for Toro Rosso in 2015." It's not clear if he will be able to find a seat or reserve driver role at another team, or who will replace him at the Scuderia, although Carlos Sainz Jr has become the latest name in the frame. An announcement is expected early next month.
