The balance of power in Durban's Ethekwini Metro Council was tilted at the weekend by the resignation of three Minority Front councillors.
This might cost the party its seat on the council's executive committee.
The councillors - Bradley Singh, a ward councillor from Phoenix, Rodney Pillay (Arena Park in Chatsworth) and Lyndall Singh joined the DA yesterday.
This means by-elections will take place soon in Chatsworth and Phoenix, with Pillay and Singh as DA candidates.
DA leader Helen Zille claimed the move was part of the realignment of politics, with Indian voters leaving the MF - moribund since the death of leader Amichand Rajbansi - and joining the DA.
She warned Indian voters that the employment equity measures recently adopted by the ANC government meant racial quotas allowed only 3% of positions to be filled by Indians.
Saturday also marked the return of DA parliamentary leader Lindiwe Mazibuko to the campaign trail after she underwent emergency surgery a few weeks ago.
Mazibuko campaigned for her party in Phoenix and Pietermaritzburg.
Zille went from Phoenix on a tour of Chatsworth, the area with the largest concentration of Indian voters in the country.
She also visited an informal settlement in Welbedacht, situated in a valley on the boundary of Chatsworth and Umlazi.
In Gauteng, more than 2000 DA supporters risked the heat to go and listen to the party's candidate for provincial premier, Mmusi Maimane, in Tembisa on the East Rand yesterday .
Maimane urged supporters to fight for policies that created employment.
"President Jacob Zuma's cows are living in the lap of luxury while the houses of people here in Gauteng leak every time it rains and people forage in dustbins for food," said Maimane.
