MotoGP organisers have cancelled the Valencia Grand Prix due to catastrophic floods in Spain and will be now hosting the season-ending event at a different venue and date.

The death toll from Europe's worst weather disaster in five decades rose to 205 people on Friday, all but three in the eastern Spanish region.

"After carefully weighing up the potential positive impact of MotoGP racing in Valencia on delayed dates versus ensuring no single resource is diverted from the recovery efforts, the championship and local authorities have been obliged to cancel the 2024 Valencia GP," MotoGP said in a statement.

"In lieu of racing in Valencia, MotoGP will instead race for Valencia.

"The championship will put our collective efforts behind backing the relief funds already in place to ensure our positive impact can connect with the area in the way it best serves the people and communities we have been part of for so long."

MotoGP riders said in Malaysia on Thursday that it would be unethical to stage the race, scheduled for November 15-17, at Valencia's Ricardo Tormo circuit.

The race, wherever it is held, will likely decide the outcome of the championship with the tussle between Pramac Racing's Spaniard Jorge Martin and Ducati's Italian two-times champion Francesco Bagnaia set to go down to the wire.
