The MDC-T led by Morgan Tsvangirai is now the majority in the Lower chamber of Parliament. The MDC split into two factions. One faction (MDC-M), now led by Arthur Mutambara contested the elections to the Senate, while the other, led by Tsvangirai, opposed to contesting the elections, stating that participation in a rigged election is tantamount to endorsing Mugabe's claim that past elections were free and fair. The opposition parties have resumed participation in national and local elections as recently as 2006. The two MDC camps had their congresses in 2006 with Tsvangirai being elected to lead MDC-T, which has become more popular than the other group.
