( CNN ) -- Williams have become the first of the 10 current Formula One teams to confirm their entry for the 2010 world championship . Williams have become the first of the current F1 teams to confirm their 2010 world championship entry . With the deadline for entries closing on Friday , Williams have been forced to act , making it clear their position in no way undermines the unified efforts of the Formula One Teams ' Association in their ongoing debate with governing body FIA with regard to next year 's proposed rule changes . On Sunday , the teams handed FIA chief Max Mosley a letter in Monaco demanding he scrap the 2010 rules , notably the budget cap and the prospect of a two-tier championship , in return for their commitment to the sport through to 2012 . That was despite the fact Mosley had earlier claimed that progress was being made in the on-going dispute . Despite the continued furor , and with the clock ticking towards the deadline , Williams have had to step forward . `` We can confirm we have submitted our entry for the 2010 Formula One world championship , '' confirmed Williams chief Adam Parr to Press Associations Sport . `` We have done that , because we have a contract with Bernie Ecclestone 's Formula One Management , and also with the FIA , called the Concorde Agreement . `` We extended that for five years up until the end of 2012 . Bernie has honored his obligations to us under that agreement . We have been paid in full for our participation . We feel morally and legally obliged to honor our side of that contract . `` Secondly , we are a Formula One team . We do n't do anything else . It is something we have been doing for 31 years . It is very important for our employees , sponsors and fans to know we will be in Formula One for next year and many years to come . '' Parr is eager to stress Williams have not broken ranks with FOTA , that the team remains fully committed to the organisation and their efforts to build a relationship with the FIA for a better F1 . `` We joined FOTA last year , and we 're absolutely committed to FOTA , '' insisted Parr . `` FOTA has done a tremendous job in many ways , such as reducing costs and helping Brawn GP get through their difficult times over the winter . `` A lot of credit for that must go to ( Ferrari president and FOTA chairman ) Luca di Montezemolo , as well as the other teams for their support . `` We want FOTA to continue their discussions with the FIA , who have made huge concessions , more than I thought possible . Max Mosley has been very conciliatory . But what we have here is a marriage . It 's too important for everyone for that to break up . '' With Ferrari the leading team in taking the fight to the FIA , the next few days are crucial to the future of the sport . Parr added : `` We have 10 teams all committed to Formula One . `` But the FIA is right in saying it is both necessary and opportune to create the opportunity for a number of new teams to come into the sport . `` In that context we can not delay the entries . We are trying to be reasonable and find a sensible solution . ''
