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.
