Only in his early 30s and with enormous energy and an endless fighting spirit, he is sharp and knows how to think strategically to achieve political objectives. Over the past three months of a gruelling political battle against the Thaksin regime, Suriyasai has played a key role in designing both the offensive and defensive strategies of the PAD. Both the Thaksin government and the PAD have had equal intelligence information about their moves and countermoves while trying to outwit each other for political advantage.

The PAD is a political phenomenon, a reaction against the repressive Thaksin regime. Although Thais in general do not trust some key members of the PAD, they are willing to give the organisation the benefit of the doubt as it focuses its energy on resisting the Thaksin machine. There were some 10 million "no votes" on April 2, reflecting widespread resentment against Thai Rak Thai among middle-class voters.

A protege of Phiphop Thongchai, Suriyasai has risen to meet the challenge of Thai politics being at a crossroads. Over the past two years, he succeeded in becoming secretary-general of the Campaign for Popular Democracy. The organisation's aim is to enhance the role of people's politics.

You must agree that Suriyasai has passed a critical test. He now has the larger-than-life image of a political activist. Speaking to Manager Online, Suriyasai said he slept very few hours at the height of the battle. With his busy travel schedule, he has had to snatch naps in taxis, buses and planes. When the PAD camped out at Sanam Luang or Government House to rally against Thaksin Shinawatra, he could wake up late. But then he'd have to travel upcountry to meet with PAD supporters.

It was probably the most intense period of his life, and he admitted to taking precautions. He received late-night calls threatening his life. Sometimes he deliberately avoided answering his mobile phone, resulting in some 50 or 60 missed calls. When meeting strangers, he had to keep his guard up. If they were friends, then it was all right; otherwise, he had to stay alert.

He spoke a little about his private life, how he now had little time for subjects close to his heart. But he may plans to go to the US or the UK for three or five years after this episode. Or he may set up a political party. He'll decide next year.

For now, Suriyasai can bask in his success, which has come at a big price, because his life has completely changed, for better or for worse.

Keep an eye on the future of this young man, who will be a force in Thai politics for decades to come.
