People have been encouraged to attend VJ Day events on Saturday amid reported terror threats in London.
Security is expected to be tight at the ceremonies, which will be attended by the royal family and the Prime Minister, and police said the public should remain "vigilant and alert".
Scotland Yard said a large security operation would be in place and people should go ahead with plans to attend or take part in events as normal.
It comes after the Mail on Sunday reported on an alleged terror plot targeting the Queen, while Sky News said an undercover journalist was told by a jihadist that the VJ commemorations were a target.
Buckingham Palace has refused to comment on the reported threat, with a spokeswoman saying they did not comment on security matters.
Following the media reports of terror fears, Scotland Yard issued a statement saying it would like to reassure the public they "constantly review security plans for public events, taking into account specific intelligence and the wider threat".
It added: "Our priority is the safety and security for all those attending or involved, the public are encouraged to continue with their plans to attend or take part in events as normal."
Commander Dave Musker, who is in charge of the policing plans, said they were working hard to ensure the event was "safe and secure".
"We have been working closely with our partners in the Ministry of Defence and the Royal British Legion, amongst others, to ensure the day's commemorations pass off peacefully," he said.
"I would also like to reiterate our long-standing advice to residents and visitors to remain vigilant and alert.
"As ever, we would urge the public to get in touch to report anything suspicious by calling the confidential anti-terrorist hotline on 0800 789 321, or 999 in an emergency."
