Jenson Button will be back in the F1 paddock next season when he joins Sky F1's team of commentators for 2019.
The 2009 world champion, who remains an active driver, winning the Japanese Super GT series this year, contributed to Sky F1's expert line-up last summer at the British Grand Prix.
"I'm incredibly excited to join up with the Sky Sports team again," said Button.
"Working with them at Silverstone this year gave me a taste of television broadcasting, one that I thoroughly enjoyed and look forward to again in 2019."
Sky has retained the exclusive rights to F1 for the United Kingdom for the next six years, and will broadcast live every practice session, qualifying session and race on F1's 21-race schedule in 2019.
"Jenson's arrival is fantastic news for our customers and for motorsport fans," said Scott Young, head of Formula 1 at Sky Sports.
"We have a world-class presenting team and we now add the unique insights from another world champion.
"This will elevate our coverage of Formula 1 in what is our first year of exclusivity in the UK."
