Britain's oldest war veteran has paraded past the Cenotaph in a vintage car, to represent the millions who served in the Great War.
Henry Allingham is Britain's oldest war veteran at the age of 107
Henry Allingham, 107, of Eastbourne, served as a mechanic in the Royal Navy, servicing air craft.
He was one of three veterans aged over 100 to join in the parade.
It is believed to be the first time in 10 years that veterans of the 1914-1918 conflict have joined in the march-past in central London, organisers said.
Great War survivors
The trio represented the 27 surviving Great War veterans in Britain.
Bill Stone, 103, of Oxfordshire, and Norman Robinson, 102, of Nottingham, passed the national war memorial in Whitehall with Mr Allingham in an chauffeur-driven 1911 Austin.
Mr Allingham said that we need to keep remembering the Great War.
"I do, because it happened to me and not just me, but for all of us.
"We couldn't have given more," he said.
In World War One, 5.7 million British men served, 702,410 lost their lives and 1.6 million were wounded, according to War Office statistics from 1922.
Denis Goodwin, founder of the World War One Veterans Association, said: "Henry joined the Navy in 1914 and worked in Great Yarmouth servicing planes to bomb enemy submarines in the North Sea.
"He witnessed the Battle of Jutland and served in Dunkirk and Ypres."
He said he was determined to make sure the World War One veterans were represented in the march when he realised that 16 had died in the last year.
