Eight per cent of British men doubt the paternity of their child, a recent survey claimed.
According to the YouGov poll, 1.2 million men across the country are concerned that they may not be the biological father of their children.
The number of fathers with doubts varies by region – from 16 percent in London, Northern Ireland and the North East to just three per cent in Yorkshire and Scotland, the Mail reports.
Doubts varied according to occupation, marital status, and age, with older fathers being the most secure about the paternity of their children. Just five per cent of fathers over 55 admitted to doubts, compared to 15 per cent of fathers aged 25 to 34.
Meanwhile, six per cent of mothers in the North West said they were unsure who the father of their children was.
