The GP2 race winner has been in talks with Manor for several months now, and at the end of last year the Indonesian government agreed to bankroll up to £10 million of support behind him in case he could not reach set sponsorship targets.

Haryanto and his manager Piers Hunnisett have been working hard ever since, trying to put together a support package that would be enough to land the Indonesian the F1 drive he so desires.

And amid reports over the past 24 hours that Manor's 2015 driver Will Stevens is out of the running, Haryanto's backers are now ready to reveal their plans for the season ahead.

Indonesian oil company Pertamina has invited journalists to its headquarters in Jakarta for an event on Thursday afternoon that will discuss Haryanto's 2016 F1 plans.

Manor has already announced that Pascal Wehrlein will drive one of its cars this season, while it would ideally want its second driver in place by the time testing gets underway next week.
