Thailand¡¯s most successful political party of modern times is heading for its worst election performance, with its founder jailed and his daughter ousted as prime minister last year by court order.

Polling indicates Pheu Thai, the latest incarnation of the organization founded by telecom billionaire Thaksin Shinawatra, is currently third, ahead of elections this weekend.

A nationwide survey of 2,500 people by the independent National Institute of Development Administration (NIDA) suggests Pheu Thai would capture only around 16% of the vote, a fraction of the support it commanded in its heyday.
