Meet the four-year-old "genius" can identify all 50 US states on a map - as well as all the major cities in the UK and name all 195 flags of the world."

Arthur Weekley has been interested in flags since he was three after his dad, Bobby, who was 30, bought him a puzzle with different flags.

Since he was gifted more maps for Christmas, Arthur has now memorized the names and locations of all the US states, UK cities and has started on India.

Mum, Jas, 29, started testing Arthur on his knowledge and he is now able to remember every single state and national flag.

Bobby, a charity manager from Rayleigh, Essex, said: "It's all self-taught. We don't go through and teach him everything; he does it alone. "

"He can point out states without name [prompts] now, which is the same as in the UK."

"If there were a competition in the house, he would win it out of the three of us 100 percent."

"My flag knowledge has improved a lot than it was before. He teaches me most of the time when it comes to flags."

When Arthur was two years old, Bobby bought him a puzzle with flags from different countries.

From then on, Arthur started remembering the flags of different nations, including Uganda, Pakistan, and Turkmenistan.

Bobby said: "Now he's four, and knowing all the flags, he has memorized all the shapes of countries and where they are."

"It's imposing and still shocks us now. "

"It's incredible; I show it off everywhere we go. Everyone loves to test him, and he enjoys the challenge."

Bobby says that people think he cheats and helps Arthur out, but when Bobby guesses the flags at a family event, he "amazes" them."

He said: "He showcases his skills at family parties, and I tell people to show him a flag, and he immediately gets it."



"People think I cheated and told Arthur before, but I haven't."

"It always amazes me every time he does it."
