Then team confirmed that the Indonesian has lost his race seat after failing 'to meet his contractual obligations'. However, he will be retained as the team's reserve driver.
"Rio has been a much-valued member of our team since January, when we signed a contract with him for this season," said Manor’s racing director Dave Ryan. "Some time ago, his management indicated that they were experiencing difficulties honouring the obligations of that contract beyond the Hungarian Grand Prix."
"Rio’s team have worked tirelessly to try to resolve that situation with his Indonesian backers and we have supported those efforts as much as possible, including allowing Rio to race in Germany," Ryan continued. "Unfortunately we reached a point where, in the best interests of the team, we were forced to explore other options for the remainder of the season."
"We are very pleased to continue our support for Rio’s Formula One ambitions, by offering him a reserve driver role for the rest of the current season. We very much hope that he will accept that offer."
Manor are expected to announce Esteban Ocon as Haryanto's replacement in due course.
