Breakaway series could doom several F1 venues

If marquee names like Ferrari carry out their threat and pull out of the Formula One championship to form a rival series, Singapore will probably not be able to host a leg of the new race just yet. It is understood that the Republic's five-year deal with F1 commercial rights holder Bernie Ecclestone, which runs out in 2012, has a clause that prohibits this. Other cities on the 17-race calendar, such as Melbourne, are believed to be bound by similar clauses.
