R&A chief executive Martin Slumbers insists there has been no intelligence surrounding any potential protest at The Open this week but remains confident in the 'significant' security procedures which have been put in place.
Slumbers said the event had been targeted at St Andrews last year - there were rumours of a potential Just Stop Oil intervention - but nothing public materialised after security was increased at specific locations.
Players this week have been advised not to get involved in any protests which may take place after the environmental group targeted Wimbledon and the Ashes Test at Lord's, where England wicketkeeper Jonny Bairstow carried one protester off the pitch.
