Banharn Silapa-archa persuaded Pongpol to join Chart Thai Pattana after his political ban was lifted, Porapol said.
Pongpol, who served as an MP and cabinet member in the governments of Thaksin Shinawatra, had been a co-founder of the Chart Thai Party. He is also a novelist, having written several books under the pen name Paul Adirex.
Spokesman Watchara Kannika said having both father and son in the party’s ranks would strengthen Chart Thai Pattana, thanks to Pongpol’s many political connections and Porapol’s promising future as a bright young politician. Party leaders would soon decide about what positions the Adireksarns would take.
