Paul di Resta is officially back in Formula 1 as Williams have confirmed him as their reserve driver for the 2016 World Championship.
The Scot last raced in Formula 1 in 2013 before he lost his Force India seat which prompted a return to DTM with Mercedes.
Although it appeared as if his F1 career was over, Williams have surprised many by announcing di Resta's return.
Alongside his DTM drive with Mercedes, he will fill the role of the team's official reserve driver, spending extensive time with the team at races to ensure he is fully accustomed to the controls and procedures of the FW38 while also putting in time in the simulator.
"I am delighted to be joining Williams as reserve driver and look forward to the 2016 season," said the 29-year-old.
"It will be a busy year combining both driving in DTM with Mercedes AMG, and attending the Formula One grands prix in my new reserve driver role.
"I will be giving my full support to both and look forward to the exciting possibilities the year has ahead. I would like to thank Claire and Williams for the opportunity to be part of the team."
Deputy team principal Claire Williams added: "We are delighted to welcome someone with Paul’s experience to the team. Having competed in 58 Formula One races throughout his career Paul’s racing knowledge will be invaluable.
"We are also confident that given his recent Formula One and current DTM experience Paul will be able to confidently step into the FW38 and assist with our 2016 campaign."
