Mercedes and Williams are believed to be the two major established teams that have yet to agree to Bernie Ecclestone’s terms for a new 2013 Concorde Agreement.
It’s thought that Mercedes is simply not happy with the commercial arrangements currently on offer.
Ecclestone announced today that the majority of the teams had already agreed, and named Ferrari, McLaren and Red Bull. To that list can be added Toro Rosso and Sauber, who also made an early exit from FOTA.
The majority of seven is believed to be made up by Lotus and Force India. Aside from Mercedes and Williams the three youngest teams are yet to agree, but obviously they are not regarded as a priority by Ecclestone, who traditionally has to get the big players in line first.

Would McLaren be out of the agreement if Ron was still in charge? Ron, Ken and Frank opposed the ’97/’98 agreement when floatation was (last?) mentioned. Nice touch that Mercedes still use Tyrrell’s Companies House registration number.
FOTA seems a bit pointless now.
