The Formula One Teams Association has welcomed back Williams and Force India into the fold after a rule spat.Williams, one of Formula One's most storied teams, and Indian team Force India were thrown out by FOTA this summer. They lodged official entries to race next season while the leading teams discussed forming a breakaway series because of controversial 2010 regulations.

Governing body FIA has since amended those regulations to the satisfaction of FOTA teams, which include Ferrari, McLaren, Renault, Red Bull, Toro Rosso, Toyota and Brawn GP. At least three new teams will enter next season. BMW Sauber is looking for  a buyer after the German manufacturer said it will withdraw from the sport after this season.
