Spectators have been urged to avoid a famous part of the London Marathon route on Sunday amid a planned protest, despite Extinction Rebellion saying it has no plans to intentionally disrupt the race.
The climate group's scheduled four-day protest in central London from Friday to Monday could see some 30,000 of its supporters in the Westminster area for the "final stretch" of the marathon on Sunday.
Hugh Brasher, event director for the TCS London Marathon, advised people to "watch the marathon from other locations and avoid the Parliament Square area on the day", as the square and "immediate surrounding area" will be "very busy".
