Akanat entered politics shortly after graduating from Oxford, becoming private secretary to his stepfather, Suthep, then Deputy Prime Minister.^[2] Akanat was subsequently elected a Democrat Member of Parliament representing Bangkok in the 2011 general elections. At 25, he was the youngest MP elected that year. He and other members of his family received acclaim for his work during the 2011 Thailand floods, where he delivered food and other supplies to aid kitchens in Bangkok and Southern Thailand.^[3]

In June 2013 he resigned from Parliament, to help lead the People's Democratic Reform Committee dedicated to ousting the government of Yingluck Shinawatra, and served as the organisation's spokesman.^[3] After the removal of the Yingluck government and coup d'état in 2014, Akanat joined Suthep in being ordained as a monk for a year.
