An opposition Democrat MP, who is also a doctor, insisted that he should go on leave and get treatment for showing symptoms of a mental and behaviour disorder - a claim roundly dismissed by the Prime Minister.
The Bangkok Post yesterday reported that the Democrat MP, Dr Malinee Sukvejworakij, held up a book entitled Sick People Who Ruled The World, as she attacked Mr Samak for his 'aggressive behaviour and bad temper'.
She said there was medical evidence to confirm that the Prime Minister's acts of glaring at reporters and ordering cake and red cordial drinks like a child reflected low IQ and EQ.
The newspaper said she referred to his moody look prior to a luncheon with coalition partners early this month.
'A leader needs both mental and physical strength. Mr Samak should take a break to seek medical help,' the paper quoted the MP as saying.
Responding to Dr Malinee's claims, Mr Samak said her medical licence should be reviewed.
'It's the first time I've seen a doctor diagnose a patient on the floor of Parliament.'
He maintained that he had quarterly health examinations, adding that his surname meant 'good doctor'.
And he said he glared at reporters only to show his displeasure.
'If I am crazy because I glare at reporters, then all actors in soap operas will have gone mad; they glare at each other all the time. And there's no point worrying about my liking red drinks.'
The Prime Minister added: 'Would you like to compete with me in a brain game, like a memory test?'
