The final undisturbed event on the World Para Athletics Grand Prix schedule has been postponed, meaning the entire season has been wiped out by the coronavirus pandemic as things stand.

The Tunis Grand Prix was due to take place from June 26 to 28, but has now been postponed.

It was the last Grand Prix meeting of the series when the schedule was first released, and the event was also the last one not yet postponed or cancelled.

Of the nine other events on the schedule, six have been cancelled and three have been postponed.

Local organisers and World Para Athletics are still holding out hope that the Paris Grand Prix, Arizona Grand Prix, Tunis Grand Prix and European Championships can be rescheduled. 

Polish city Bydgoszcz was due to host the 2020 European Championships.

World Para Athletics said it "regrets" the latest postponement, but that it was the only option as "the health and well-being of all those involved" is the main priority.

The Tokyo 2020 Paralympics - the event for which many of these Grands Prix would have served as a warm-ups and opportunities to secure qualification - were postponed until 2021 and will now begin on August 24, with the Closing Ceremony due to be held on September 5.

As a direct result, 2021's World Para Athletics Championships have been postponed until 2022.
