Rio Haryanto's plans to return to F1 have been dealt ꦜa hefty blow after state-owned energy company Pertamina announced it would be dropping its sponsorship.

Haryanto became the first I🌊ndonesian driver in F1 history last year when he joined Manor alongside Pascal Wehrlein but replaced by Esteban Ocon after 12 races when his sponsorship fell through.

The 23-year-old stated he will look to return to the sport in 2017 with possible options at Sauber or a comeback at Manor - who are currently in takeover talks - but his hopes have taken a hit by the loss of Pertam♈ina as backers.

"This year there will not be a continuation of participation by Pertamina in F1," a spokesperson told Reuters. "Of course we regret 🌞this very much, but we have already made maximal efforts for Rio and Indonesi🌸a."

Haryanto will look f♛or new spo𓂃nsors to cover the reported ?4.23M funding gap which Pertamina stacked up as part of the Indonesian driver's deal with Manor in 2016.

Sauber is likely to confirm Mercedes-backed Pascal Wehrlein alongside the already-announced Marcus Ericsson having been overlooked in favour of Valtteri Bottas aꦿs Nico♏ Rosberg's replacement at Mercedes for 2017.

Felipe Massa is believed to make a U-turn on his decision to re⛦tire from F1 and return to the Williams f💧old with Bottas switching to Mercedes.
