Every government has signed up to a voluntary legal commitment under at least one of the international covenants and conventions based on the Universal Declaration of Human Rights. But who is holding them to account? Our mission is to make it known that these conventions are good tools for civil society to hold their local authority, their government and businesses accountable.

I have a sense that South Africa is my other country apart from my native country that I particularly love, [that I] want to see succeed, and I did really want my message to be listened to.

The burden of health care shouldn't be borne by the poorest families. We should have equity within health systems so that families are able to cope with serious illness and not be driven into poverty and relationship breakdown because they don't have access to health care.

Look, you are interested in trying to make sure that governments keep a clean environment, have regard for the lifestyles of indigenous peoples, and work for fair trade rules. Well, it's exactly the same for human rights - from non-discrimination to the basic rights to food, safe water, education and health care. We are talking rights not needs. There are standards that governments have signed up to - but nobody is holding them to account.

Climate change is the greatest threat to human rights in the 21st century.

I believe we should try to move away from the vocabulary and attitudes which shape the stereotyping of developed and developing country approaches to human rights issues. We are collective custodians of universal human rights standards, and any sense that we fall into camps of "accuser" and "accused" is absolutely corrosive of our joint purposes. The reality is that no group of countries has any grounds for complacency about its own human rights performance and no group of countries does itself justice by automatically slipping into the "victim" mode.

South Africa is regarded as being an extraordinarily important country - not just for South Africa, but for Southern Africa, for the BRICS, working now in a new way in which power is becoming more shared - thankfully.
