Vergne announced on social media that he would not be driving for Toro Rosso in 2015.
Jean-Eric Vergne has been dropped from Red Bull junior team Toro Rosso, the Frenchman has announced.
The 24-year-old had hoped to retain his seat after teammate Daniil Kvyat was promoted to Red Bull following Sebastian Vettel’s highly-publicised move to Ferrari.
However, the 2010 British Formula Three champion took to Twitter to announce his departure from the Italian-based outfit.
Despite a good season & 22 pts, I'll not drive anymore for Toro Rosso in 2015. Thanks for those years. Let's go for another big challenge.

Toro Rosso have not yet announced his replacement, but it is believed Carlos Sainz Jr. is the favourite the land the seat.
Sainz, the son of the great rally driver of the same name, drove for Red Bull during the two-day test in Abu Dhabi this week.
The Spaniard, along with Alex Lynn and Pierre Gasly, are in the running to partner the already-contracted Max Verstappen in 2015.
Despite a solid year, it seems Vergne will be without a full-time seat in F1 next year and may have to settle for a reserve/test spot or go to another category.
