Silverstone bosses are leaving nothing to chance as they bid to prevent Just Stop Oil protests from marring the British Grand Prix.
The military will be on hand to deal with any activists, amid fears there will be a repeat of the scenes which marred the race in 2021. Following an opening lap incident involving Alfa Romeo's Zhou Guanyu, five spectators made their way onto the track, and were later arrested and found guilty of risking "serious harm" to F1 drivers.
But that hasn't deterred the group from seeking publicity at further high profile sporting events. The World Snooker Championship was tainted by a protestor evading security and pouring powder on one of the table cloths, and the recent Ashes Test at Lord's saw players act to prevent members reaching the wicket.
