A great-grandfather living in Britain has staked his claim as the oldest man alive in the world - aged an impressive 113.
Ghahreman Pardis took the World’s Oldest title following the death of Jiroemon Kimura, who passed away in Japan yesterday aged 116.
Mr Pardis’ Iranian birth certificate says he was born on November 2, 1903, which officially makes him 109.
But his family claim his papers were doctored twice so he could dodge national service in his home country.
They say he was actually born in 1899, which makes him a whopping 113 years and 69 days old - and the oldest man alive on the planet.
His true age became masked when Mr Pardis faced conscription as a teenager in Turkey where he was as a leading boxer, his relatives claim.
Government chiefs wanted to keep the sporting champion so they altered his passport to show his birthday as two years later - in 1901 - ensuring he would not be drafted.
Then during his 20s Mr Pardis moved to Iran where he became a sports coach and key figure building sports facilities in the country.
Iranian officials were so impressed with his role in the country they too altered his date of birth by two years so he could avoid joining the army.
Mr Pardis' family say they were regularly told about the age-change while they were growing up but gave it no importance - until Britain's oldest man died in January this year.
Now former world's oldest man Jiroemon Kimura has died Mr Pardis' proud children, who all live in Britain as UK nationals, believe their father is the rightful owner of the title.
Mr Kimura, who was born on April 19, 1897, died at the age of 116 yesterday in Japan.
He held the record for not only the world's oldest person but also the world's oldest man to have ever lived.
Mr Pardis' son, Hamid Pardis, 61, who moved to Britain in 1975, and set up his own restaurant in Aylesbury, Bucks., yesterday said: 'It would be amazing if my father was confirmed as the world's oldest man.
'He always told me that they changed his passport because they wanted him to help them with their colleges and sports stadia.
'They even changed his name to Ghahreman - turkish for 'champion' - because he won so many boxing matches.'
Mr Pardis' family say the young Mr Pardis was always told he would live a long life.
His daughter Shohreh Pardis, of Aylesbury, Bucks., said: 'When he was very young somebody told him he was going to lead a very long life.
'Now he has told us he is going to live to 120. The rest of the family have health problems but he has nothing, apart from his hip.'
Mr Pardis, of Aylesbury Vale, Bucks., was born in Iranian Persia before moving to Turkey at the age of five to be closer to his brothers, who all worked in the country.
In his new country he was regarded as a talented sportsman, excelling in boxing, wrestling, football, volleyball and basketball and he avoided conscription.
He married his wife of 68 years Maryam, now 88, in Iran, in 1944, where they lived together until moving to London to be closer to the three children who worked there, during the 1960s.
Mr Pardis later moved to Aylesbury, Bucks., during the mid 1980s to be closer to family, where he still lives with his wife, despite being wheelchair bound after multiple hip replacements.
His nephew (his sister's son), aged 92, has repeatedly vowed to Mr Pardis family he is 21 years younger than the potential record-breaker - confirming his 113-years claim.
Japanese woman Misao Okawa from Osaka, who is 115 years old, is expected to inherit the title of world's oldest living person.
She is already considered the world's oldest living woman.
