 On 18 July 2007, the MP formalized an alliance with the Cameroonian Democratic Union (UDC); as part of this agreement, the parties decided not to run candidates in the same constituencies.On 17 July, John Fru Ndi, the leader of the opposition SDF, which suffered from divisions in the years preceding the election, claimed that the preparations for the elections were plagued with irregularities, including poor distribution of voter registration cards (with some people receiving multiple cards and others receiving no cards) and the redrawing of electoral districts even though census results had not been published.Fru Ndi said that the election would not be transparent and blamed President Paul Biya for this; he said the ruling RDPC wanted a two-thirds parliamentary majority so that the constitution could be changed in order to allow Biya to run for president again in 2011.
