LONDON (Reuters) - British Grand Prix organisers have set an end of April deadline to decide whether the country's Formula One race goes ahead as scheduled in July or becomes another casualty of the coronavirus.

The race, a highlight of a British sporting summer that looks likely to be wiped out by the pandemic, has been the best attended on the F1 calendar in recent seasons with a total crowd of 351,000 last year.
