Suan Dusit Poll says errors in its final poll in the lead-up to Sunday's governor election led the pollster to incorrectly predict that Pheu Thai candidate Pongsapat Pongcharoen would win.

"We accept the mistake and will look into the cause of the errors to improve the quality of our polls," Mr Sukhum said. "We will also ensure that every poll is well-planned and every piece of information will be double-checked."
