Dashing, ambitious, young and with the power to call the shots, Khairy Jamaluddin, KJ to his friends, tends to drive Malaysian politicians mad.
'He gathers political enemies like flies to carrion,' said veteran political analyst M.G.G. Pillai. 'He has everything going for him, and because of that, in the faction-riven world of Malaysian politics, he invites hatred and jealousy.'
His detractors have dubbed him the 'most powerful 30-year-old' in the country. He is the man regulars in Malaysia's internet chat rooms love to hate.
He was in the spotlight again this week after buying M$10 million ($20.61 million) worth of shares in ECM Libra, a financial consultancy favoured by the government. Mr Khairy is holidaying in Australia, but ECM shares are rising on the back of his purchase and on speculation his father-in-law and Prime Minister Abdullah Badawi might give the consultancy an investment banking licence.
But a lack of transparency on the deal has aroused suspicion.
'He has to tell the people where he got so much the money to buy the shares,' said opposition politician Hussam Musa. 'We are not screaming corruption ... it could be a friendly loan or a bank borrowing, but just tell us.'
