Three of the current series' episodes have been pulled from the schedules, and it is currently not clear if the show will return, with or without Clarkson.
Hundreds of thousands of fans have already called for Clarkson to be reinstated, and Top Gear remains a hugely popular programme around the world. But would it be anywhere near as successful without Clarkson front and centre?
James May and Richard Hammond are also integral to its popularity, but could the show remain as popular with just the two of them or perhaps a new presenter?
Bookmakers have already picked the likes of Chris Evans, Jake Humphrey, Vicki Butler-Henderson and Eddie Irvine as potential replacements, but would they have the same impact? Or is it time for the show to come to an abrupt end?
