HE LOOKS pretty good for his age, given that he is officially the oldest man in the world.
After leafing through his documents recently, Chris King realised his birth certificate has him down as being born in 1858 – making him 154.
In reality, Mr King was born in 1958 and is 54.
However, he is now making a cheeky claim to the Department of Work and Pensions (DWP) for back-dated pension money amounting to almost £400,000.
Mr King, of Brantingham Walk, west Hull, said: "I only discovered the mistake a couple of days ago as I was going through some documents.
"This is a legally binding document, so I am going to approach the DWP to see about getting 90 years of pension backdated.
"I sat down and worked out I should be getting £375,000 and I'm going to fight to get this.
"I have never come across anything like this before but it isn't my mistake."
Mr King, a security officer, was adopted when very young, which is why the mistake has only just come to light.
His twin sister's birth certificate has the right year, making him 100 years older than her.
Mr King does see the funny side.
He said: "I do find it rather humorous and it is strange to think I am probably the oldest man in the world.
"At my next birthday I'm not sure how I'm going to fit 155 candles on to my cake.
"I might write to the Queen and see if she will send me a card next time."
The DWP has dismissed Mr King's attempts to claim any backdated pension.
A spokesman said: "We would not entertain the idea of giving him a backdated pension.
"It is clear he isn't that age and it is an obvious mistake.
"He needs to go to his local register office and get the mistake corrected."
