Mr Allingham gave the public a glimpse of his dry sense of humour when he attributed his longevity to: "Cigarettes, whisky and wild, wild women."

His funeral will take place later this month at St Nicholas' Church in Brighton.

Henry and his wife of 53 years Dorothy moved to Eastbourne in 1960, she died ten years later in 1970.

Henry had two daughters but outlived both of them. He also had five grandchildren and 12 great grandchildren, 14 great-great grandchildren and one great-great-great grandchild.

His father died when he was 14 months old and he was brought up in London by his mother.

She encouraged him to join up as soon as war broke out in 1914.

When she died the following year he joined the Royal Naval Air Service in September 1915 before transferring to the RAF in April 1918 and was the last survivor of the Battle of Jutland.

His friend, Dennis Goodwin, said he was one of an "extremely unique and special generation of people".

He said: "Not only did they survive the most horrific war of humanity but they had a new life to begin afterwards in an era of depression, and they did it admirably.

"I'm one of the products of that generation and I think my generation and other generations afterwards should remember that; it's a legacy they should create and keep in their memories."

Mr Goodwin, who was a regular visitor to Mr Allingham at St Dunstan's, described him as "an exceptionally good friend".

He added: "He was almost a surrogate father to me, we shared life together."

Describing the last few months of his life, he said: "He wasn't in the best of health. He wasn't eating.

"He often said to me he'd love to eat something good and have a drink like the old times but his tastebuds had gone, and I think it really frustrated him."

Prime Minister Gordon Brown said: "I had the privilege of meeting Henry many times. He was a tremendous character, one of the last representatives of a generation of tremendous characters.

"My thoughts are with his family as they mourn his passing but celebrate his life."

Mr Allingham became the world's oldest man on June 20.

Guinness World Records confirmed his title after the previous holder, Tomoji Tanabe, died aged 113.

When asked in an interview what his motto for life would be, Mr Allingham said: "Be the best you can be"
