Johannesburg - Deputy President Kgalema Motlanthe said on Monday that the only way to continue Nelson Mandela's legacy was to conquer racism and sexism.

“The most enduring monument we can build to Mandela's memory is to strive for human solidarity to conquer racism and sexism, to eradicate social inequalities... and uphold human rights culture,” he said.

He was speaking at a memorial service for Mandela at Westminster Abbey in London.

“We can no longer pretend that racial discrimination is a figment of the imagination, in a world where heightened racial consciousness confines millions to the margins of global society.”

A copy of Motlanthe's speech was sent to Sapa.
