And he's aware enough of his Geordie background to declare, "I am a fan of The Toon!"
Despite being 44, he's only seen The Mags win one major trophy - back in 1969! "It was the right time to take the bairn back home", said his dad.
Drs Athasit and Sodsai Vejjajiva went back to Thailand when their son was still a boy, but Newcastle United stayed with young Abby.
Born into a family with deep roots in Asian politics, his family has had good relationships with the Thai ruling elite from as far back as the 18th century.
But in one interview he admitted: “If I was not me, I would like to be a Newcastle United striker.”
His task as Thailand’s fifth Prime Minister in two years is to restore the country’s battered economic confidence, cool down its overheated political climate, and impose his authority on a cabinet formed during days of bargaining with his coalition partners.
But he'll have his work cut out. He's no mate of former Manchester City owner and Thai PM, Thaksin "Frank" Shinwatra, seen here with Abby's Toon shirt.
Outside the parliament, about 200 Thaksin supporters reacted furiously to what they called a “silent coup”, hurling barricades at the gates and stopping MPs from leaving. Insiders say the new coalition may only last a few more weeks.It sounds like any Saturday at half-five outside St. James' Park each time Mike Ashley shows his face! - Sack The Board, Sack The Board, Sack The Board!!
Soccermongery wishes him well. The big question is: will he outlast Alan Shearer in keeping his top job?
