I don't like a bipolar or a unipolar world. I like a multipolar world but on many occasions people have been surprised that South Africa has not seemed, internationally as well as internally, to take a decision that affirms the true values of your Constitution and the vision of those who were there at the beginning - Madiba himself and others.

The aim of human rights, if I may borrow a term from engineering, is to move beyond the design and drawing-board phase, to move beyond thinking and talking about the foundations stones - to laying those foundation stones, inch by inch, together.

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.

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.

The governments are seen to be less effective than they used to be. The private sector is perceived as being so much more efficient, and so globalization implies a transfer of power to the private sector.

Young persons, because of their immaturity, may not fully comprehend the consequences of their actions and should therefore benefit from less severe sanctions than adults. More importantly, it reflects the firm belief that young persons are more susceptible to change, and thus have a greater potential for rehabilitation than adults.

The UN may not be very effective but I am a fan of the idea of the United Nations. I have been there, I know the problems. To parody Winston Churchill: It is the worst system, except we don't have any other.
