Kimi Raikkonen will return to Ferrari and join Fernando Alonso for the 2014 Formula 1 season, the team has confirmed.
Ferrari's official announcement of a two-year deal confirms a move that seemed increasingly inevitable in recent days.
Raikkonen was in the running for the second Red Bull seat alongside Sebastian Vettel, but the champion squad as Mark Webber's replacement instead.
It then seemed most likely that Raikkonen would remain at Lotus for a third season.
But assurances from the team about its future investment and technical packages were , and Lotus was not yet in a position to provide those.
With Felipe Massa announcing Tuesday night that he would at the end of this season after eight years, and Raikkonen's rival candidate Nico Hulkenberg informed on Wednesday morning that he would not be required, the 2007 world champion's return to the Scuderia was sealed.
Raikkonen previously drove for Ferrari from 2007-09.
He came from behind to deny McLaren duo Lewis Hamilton and Fernando Alonso the title in his first season in red, but had to play second fiddle to teammate Massa's championship push in 2008.
After a disappointing 2009 campaign, Raikkonen left Ferrari and Formula 1 to pursue a career in the World Rally Championship.
This proved unsuccessful, and after dabbling with NASCAR Truck racing and testing Peugeot's Le Mans car, he headed back to F1 with Lotus last year.
An immediate frontrunner back in single-seaters, Raikkonen has been among Vettel's main opposition since his return.
