Exactly the same scenario here in Cambodia this week.
Same PM for last 25 years, announced victory few hours polls had closed despite it being obvious the new opposition had clearly won a huge majority around the Country. Demanding recounts and protests threatened this week.
approx. 1.5million voters who turned up to vote (in opposition areas) were told their names werent on the list, video evidence of the current regime voters taking 3 ballots to post and hundreds of thousands of dead relatives apparently have risen and voted at the weekend (wonder who for?!)
Pretty tense here in Phnom Penh at the moment... but its 5.04pm and its time for a beer :)
