Doha: South Korea could make a surprise return to the Formula One menu for 2015 but controversial double points have been scrapped, the sport's governing body the FIA announced on Wednesday.

Korea's provisional inclusion in a first ever 21-race calendar also featuring the anticipated return of Mexico was announced after the FIA's meeting in Doha. The ratified calendar marks the Korean race status as 'to be confirmed', with a choice of venues at either its original home in Mokpo or around the streets of the capital Seoul. South Korea, which held F1 races between 2010 and 2013, is scheduled to slot in as the fifth leg of the season on May 3.
