Royal tributes for oldest veteran
Henry Allingham wanted people to remember the toll of war
The Queen has led the tributes to Henry Allingham, the world's oldest man and one of the last surviving World War I servicemen, who has died aged 113.
A Buckingham Palace spokeswoman said, on her behalf, he was of a generation who "sacrificed so much for us all".
Mr Allingham served with the Royal Naval Air Service in WWI, later transferring to the Royal Air Force at the time of its creation.
Prince Charles and Gordon Brown have also paid tribute to the veteran.
Mr Allingham's military service took him to Ypres and the Battle of Jutland.
His life spanned three centuries and six monarchs and he had five grandchildren, 12 great-grandchildren, 14 great-great grandchildren and one great-great-great grandchild.
The prime minister, who had met him a number of times, called Mr Allingham a "tremendous character".

Obituary: Henry Allingham
Prince Charles reiterated his mother's comments, saying Mr Allingham belonged to that "incredible generation who did so much for their country".
A Clarence House spokesman said: "We owe him a huge debt of gratitude for all he has done."
Dennis Goodwin, founder of the First World War Veterans' Association and a friend of Mr Allingham, said: "Henry was truly a gentleman - his strength of character, his purpose.
"He left quite a legacy to the nation of memories of what it was like to have been in WWI," he said.
For decades, Mr Allingham buried his memories of the war, avoiding reunions and refusing to tell his family about his experiences.
But, in recent years, he started making public appearances to make sure new generations did not forget the toll of war and went on to tell his life story in a book which was published last year.
First Sea Lord Admiral Sir Jonathon Band said: "Henry will be remembered with great fondness for his strong sense of humour and joy of life, and he was an inspiration for all those serving in the Royal Navy."
And Air Chief Marshal Sir Glenn Torpy, Chief of the Air Staff, said his passing was a "milestone in history".
"Henry was an inspiration to many and his thirst for life, cheery disposition and a desire to help others was his mark," he added.
Henry Allingham dies aged 113
The veteran's death has moved people across Britain.
At Lord's cricket ground in London, a minute's silence was held to mark his passing before play resumed on the third day of the second Ashes test.
There were condolences too from staff at his Brighton care home, who said he had been very active right up to his final days and would be missed by all.
Last month, the Royal Navy hosted a 113th birthday party on HMS President in London for his family, close friends and members of the Royal Navy and Royal Air Force.
That was the last time his nephew Ronald Cator saw him.
Mr Cator said his uncle looked "very, very frail. He went downhill in the last few months."
"He used to sleep a lot at the end. He wanted to pass away, poor old boy."
His death means there are now only two British survivors of WWI - Harry Patch, 111, and Claude Choules, 108, now living in Australia.
Last month, Guinness World Records declared Mr Allingham, born in 1896, the world's oldest man following the death of another 113-year-old man in Japan.
His funeral will take place later this month at St Nicholas' Church in Brighton.
