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

Haryanto became the first Indonesian driver in F1 history l♑ast 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 ta📖lks - but his hopes have taken a hit by the loss of Pertamina as backers.

"This year there will not be a continuation of participation by Pertamina in F1," a spokesperson told Reuters. "Of course we reg♏ret this very much, but we have already made maxi🍰mal efforts for Rio and Indonesia."

Haryanto will look for new sponsors to cover the reported ?4.23M funding gap which Pert🦩amina 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 overlooke𓄧d in favour of Valtteri Bottas as Nico Rosberg's replacement at Mercedes for 2017.

F꧒elipe Massa i𝓀s believed to make a U-turn on his decision to retire from F1 and return to the Williams fold with Bottas switching to Mercedes.
