Leading figures in F1 have warned Just Stop Oil campaigners not to put lives at risk at this weekend's British Grand Prix.
A year ago, the iconic race at Silverstone was marred amid frightening scenes on the opening lap, when six spectators ran onto the track after Zhou Guanyuan suffered a crash in his Alfa Romeo. It turned out the individuals were from the protest group, and in February this year were convicted of causing a public nuisance.
And such unsavoury scenes have now become a common theme throughout other major sporing events, with campaigners disrupting the World Snooker Championship by pouring powder onto the table cloths. Last week's controversial Ashes Test at Lord's also halted on the opening day, as a group tried to make their way onto the wicket, only to be intercepted by players.
