The Briton will twin his duties with the F1 team alongside a second GP2 Series campaign with Racing Engineering.

Manor's racing director Dave Ryan said the outfit had been encouraged by King's progress after his first F1 test in Abu Dhabi last year.

“I was at the Abu Dhabi test where Jordan drove our car for the first time and he did an impressive job,” he said. “It was clear that he’d taken full advantage of the opportunity to get under the skin of the team and understand the systems, processes and people.

“Over the winter months he helped us to refine driver installation with the new chassis, pending the signing of our race drivers, so the development driver role really is mutually beneficial. We look forward to having him around the team and wish him a successful season in GP2.”

King added: “I racked up 300km in that test and loved every second in the car. But what I want to do now is race one and I’m flat out working to achieve that.

“Continuing in the development driver role with Manor Racing is key to that progression and I’m excited to be working with Dave Ryan, Pascal and Rio for the first time, as well as the guys I’m more familiar with.”
