adoption of English as an official language (in addition to the two existing official languages, French and Malagasy)
removal of the phrase "secular state" (French: état laïque) from the Constitution
Early results, with 73.18% of the vote counted, showed that turnout was around 42.43%. The referendum appeared likely to be passed because 74.93% of the voters in Antananarivo were in favour of the amendments, even though it seemed likely that in four of the five other provinces the "no" vote might have won. According to results released on 7 April, with votes from 85.47% of polling stations counted, 75.24% were in favor of the proposed changes. Roland Ratsiraka, who placed third in the 2006 presidential election and opposed the proposed changes, alleged fraud.
Official results were released on 11 April, but it was necessary for the Constitutional High Court to validate the results in order for them to be final, and this happened on 27 April.
The Judged By Your Work Party (AVI) chose to boycott the referendum, saying that it was deceitful for the referendum to describe a "yes" vote as being a vote for national development.
