Wreaths have been laid at the Cenotaph for the centenary of the Royal British Legion (RBL).
The charity marked the exact moment of its formation 100 years ago at 09:00 on Saturday with a service in Whitehall, London.
Representatives of the Royal Navy, British Army, Royal Air Force and Merchant Navy laid wreaths at the Cenotaph to replicate the same actions of that time and day a century ago.
The ceremony was led by retired Lieutenant General James Bashall, who is national president of the RBL.
Across the UK, wreaths were also laid by RBL branch members at the same time, with ceremonies held worldwide, including in Cyprus, Malta, Germany, Belgium and France.
In a video message to celebrate the charity's centenary, the Prince of Wales hailed its "constant" support of the Armed Forces community.

There were also a wealth of tributes from service personnel and members of the Armed Forces community, as well as celebrity supporters including Ross Kemp and Stephen Fry.
A special edition RBL centenary coin will also be used for the coin toss of the FA Cup final between Chelsea and Leicester City at Wembley.
RBL director-general Charles Byrne said: "In this, our centenary year, we are focused firmly on our future.
"Our proud heritage and 100 years of experience supporting the Armed Forces community have built the strong foundations of an organisation fit for the next 100.
"We remain committed to our mission to ensure that those who have given so much for their country get the fair treatment, support and recognition they deserve."
The RBL was formed in the aftermath of the First World War to fight for the rights of those who had given so much.
Today, the charity continues to provide support to the Armed Forces community and challenge injustices on their behalf.
