Marcus Ericsson has announced his departure from troubled Formula One team Caterham with immediate effect.
Ericsson has already signed a contract to race for Sauber in the 2015 season and will not now compete in the season finale in Abu Dhabi.
The Swede had been forced to sit out the previous two races due to Caterham going into administration, but the team is trying to crowd-source a return to the grid.
In a statement posted on his official website, Ericsson said: "Following recent events re Caterham Sports Limited and 1 MRT Sdn Bhd, my adviser Eje Elgh and I have decided to terminate, with immediate effect, all agreements connecting me to the Caterham F1 team.
"This is a sad day as we have greatly enjoyed working with the team through a difficult and tough season."
"I wish to thank Colin Kolles, Manfredi Ravetto, Cyril Abiteboul and every other member of the Caterham F1 team for your trust and confidence in me, and for making my first Formula 1 season an educational and unforgettable experience.
"In addition, I thank my good friend and team mate Kamui Kobayashi for being an inspiring benchmark throughout the year, and hope to see him back on the track soon."
