About 250 flag waving DA supporters singing campaign songs, were waiting for their leader Helen Zille to emerge from the Cape Town International Airport on Saturday.
Among the crowd of blue T-shirts waiting in the rain was Cape Town mayor Patricia de Lille who said she was ready to return to the position.
“If the people of Cape Town want me,” she said.
“When we won the metro in 2011 with 61 percent, that paved the way for us,” said De Lille.
The DA won 59.2 percent of the provincial vote, increasing its outright majority in the Western Cape.
The African National Congress (ANC) improved its support base somewhat and garnered 33.04 percent of the vote.
Nationally, the DA increased its support in the 2014 elections from 16.66 percent in 2009 to 22.23 percent to become the official opposition to the ANC which received a reduced majority mustering 62.15 percent (11 436 921 votes) compared with 2009 and 65.9 percent of the vote.
The results are expected to be confirmed at 6pm on Saturday by the Electoral Commission of SA (IEC).
The party will have to square up to the ANC's Marius Fransman, who will return to the province as the leader of the official opposition.
The former deputy international relations minister said he was excited about returning to the province and building the ANC structures ahead of the 2016 municipal elections.
On voting day on Wednesday he had predicted the ANC would take the province from the DA.
Zille will also have to contend with the Economic Freedom Fighters which should get at least one seat in the province's legislature.
Its president Julius Malema once called her the “madam” of the “tea girl” Lindiwe Mazibuko, DA leader in Parliament, when he was still leader of the ANC Youth League.
He made the remarks when turning down an invitation to debate with Mazibuko.
DA provincial leader in the Western Cape, Ivan Meyer said: “Helen Zille is here to stay. She's the best premier in the country.” - Sapa
