Much as I hate to have to agree with VVC in any way, I do not feel that a "State Funeral" for the last WW1 survivor is appropriate. This was done on Armistice Day 1920 for the "Unknown Warrior" (NOT Soldier) whose Body was laid to rest in Westminster Abbey after a procession through the City of London which included the unveiling of the Cenotaph. At the Abbey a Guard of Honour was provided by 100 holders of the Victoria Cross.
A more appropriate course may be to start a campaign to revert to "Remembrance Day" on the 11th of November and make it a Public Holiday as it is in Belgium, Canada, France and the USA. Australia and New Zealand have their commemorations on 25 April - ANZAC Day.
