Cope Western Cape premier candidate Allan Boesak has criticised the DA's recently-launched "Stop Zuma" campaign, saying it "reeks of swart gevaar tactics".

The Democratic Alliance was playing the man and not the policy in an effort to mobilise its support base among affluent South Africans, he said in a statement on Wednesday.

"Opposition politics should be about policy, about what the party you vote for will deliver either as an effective opposition, or as a government for the people, by the people.

"Cheap rhetoric that smacks of racist undertones, playing the man and not the policy; welcome to the world of the DA, a party infused with apartheid-style politics which has no place in our country."

Constructive solutions were what was needed.

"A more constructive approach should see slogans and campaigns that read 'Stop Crime', 'Stop Unemployment', 'Stop Poverty', 'Stop Corruption', 'Stop Inadequate Healthcare' ? ideals meaningful to South Africans," Boesak said.
