The British Prime Minister, David Cameron was reported to have left behind, his 8 year old daughter Nancy, in a local pub on Sunday.

He was there for lunch with his friends at the time of departure, David Cameron forgot to take his daughter with him from the pub, believing that she would be going in a different car than his.

Prime Minister David Cameron was having a  Sunday lunch with friends following a mix-up over which car his daughter was meant to be going home in, his Downing Street office said on Monday.

Both parents of the adolescent child were present in the pub but left in separate cars accidentally believing that the other will take her along.

They were swiftly reunited with 8-year-old Nancy, one of their three young children, but the incident will add fuel to critics who accuse David Cameron of being overly fond of relaxing, or "chillaxing" as he has called it, when not dealing with affairs of state.

It is speculated that the disclosure of this news in the Sun newspaper has the potential to embarrass Cameron, coming on the day the government launched a fresh drive to tackle "problem families" who lead chaotic lives and cost taxpayers millions of pounds in policing and welfare costs.

Cameron and his wife Samantha only discovered their eldest child was missing when they returned to their official country residence, Chequers in Buckinghamshire, 40 miles northwest of London.

Nancy had gone to the toilet and been overlooked when her parents left in separate vehicles.

"The Prime Minister and Samantha were distraught when they realized Nancy wasn't with them," said a Downing Street spokeswoman, adding that the incident occurred around two months ago.

"Thankfully when they phoned the pub, she was there safe and well. The Prime Minister went down straight to get her," she added. Agencies.
