Manor has confirmed that it has retained Jordan King as its development driver in 2016, as understudy to Pascal Wehrlein and Rio Haryanto.
King joined Manor in 2015 and tested Formula 1 machinery for the first time during the post-race tyre test in Abu Dhabi last year
King will continue his junior career in GP2 this year for Racing Engineering, after placing 12th in his rookie campaign in 2015.
"Spending time trackside with the team last year was really important for me and for where I want to get to," he said.
"I saw all the processes and techniques that go into running an F1 team, plus I got a good grasp of how the tyres work as well as the data.
"So when I got the chance to drive the MR03B in the Abu Dhabi test, it felt like I’d had a massive head-start and I was really confident.
"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."
