South Africa's main opposition party has agreed to merge with a smaller party as it attempts to erode the dominance of president Jacob Zuma's African National Congress (ANC).
South Africa's Democratic Alliance will merge with the Independent Democrats by the next national election in 2014.
The two parties have struggled to sway voters away from the ANC, which won a two-thirds majority at last year's election.
Further bolstering the opposition cause is speculation that the Congress of the People, which split from the ANC in the lead-up to last year's election, may also join the merger.
The Democratic Alliance is currently led by provincial premier Helen Zille, a white woman who admits that the new political force will need black leadership if it is to become a credible alternative government.
