Despite the terrorist attacks on London, the British Grand Prix will be held on Sunday as planned after assessing security, organisers said on Thursday.
Silverstone chiefs are confident they will not need any extra security for Sunday's 100,000 sell-out.
"Following the events that took place in London, Silverstone would like to reassure all visitors that the security of both spectators and participants is of paramount importance," said a race organiser.
"Silverstone has a well-established set of security measures in place that have been agreed and planned in detail with police and other agencies.
"Silverstone is confident that these measures are adequate to ensure the safety of all attending," he added.
