‘What are you asking?’
Prawit, who leads the Palang Pracharat Party and did not attend the vote, was asked by the female TV journalist for his thoughts on the victory.
He barked back: “What are you asking? What are you asking?” and then hit her several times on the head, TV footage showed.
Piya Tavichai, a party spokesman, said Prawit knew the reporter well and had apologised, adding that he would clarify the facts in any parliamentary process.
“He was teasing her as someone who he is close to,” he said.
“Because he was a soldier, the teasing could appear to be violent, but those close to him know that he teases like this all the time.”
The incident sparked widespread condemnation from Thailand’s media community. ThaiPBS, the country’s public broadcaster, asked Prawit to take responsibility for his actions.
Prawit is a political deal-maker and central figure in Thailand’s two decades of political strife. He was Deputy Prime Minister for nine years after a 2014 coup in which he took part.
Tewarit said he had requested an ethics investigation into Prawit through the Senate to be conveyed to the lower house of Parliament, which will have 30 days to respond. He said he was unsure what penalty Prawit could face if found guilty.
