Steenkamp and Panayiotou to be honoured in PE
Friends, family and supporters will remember the two in a march honouring victims of gender violence.
The march will be led by the African National Congress Women's League (ANCWL) and forms part of the 16 Days of No Violence Against Women and Children campaign.
Dozens of family members, friends and supporters are expected to gather at the Port Elizabeth beach front this evening to honour Panayiotou and Steenkamp.
Panayiotou was murdered in April this year. Her husband has been accused of masterminding her killing.
Steenkamp was shot dead by her boyfriend, Oscar Pistorious, in 2013.
ANCWL, Toko Xasa, says this evening's march is also aimed at honouring victims of gender violence.
