Police have ramped up security for tomorrow’s London Marathon in the wake of the Westminster terror attack.
The Met Police has warned runners and spectators to be stay “vigilant” during the race, with the force expecting millions of people to descend on the capital.
The warning comes after a police officer was shot and killed in an attack in Paris on Thursday, just one month after Met officer Keith Palmer was stabbed to death outside Westminster in a terrorist rampage that killed five innocent people.
The Met has promised a “strong and visible” presence in the wake of the attacks.
Commander Jane Connors said: “The Marathon is a fantastic event and embodies everything that’s great about London.
“Our priority is to ensure that those taking part and watching have a safe and enjoyable experience and I’d like to reassure people that there is a comprehensive policing plan in place to achieve this.
“There will be a strong, visible presence of officers along the entire route and at transport hubs across London, but if you notice anything suspicious, then please report it to us.”
Officers from the Met and British Transport Police will be patrolling the streets on Sunday, with the marathon set to start at 10am.
Some 50,000 runners are expected to take part.
Race director Hugh Braster has said there will be “really robust security measures” and that organisers have “deeply looked” into safety risks at the event.
