PERTH, Oct 30: Commonwealth leaders on Sunday defended their move to toughen support for human rights, rejecting criticism the group was becoming irrelevant and had failed at their three-day summit to hold member Sri Lanka accountable for alleged abuses.

But several leaders of the 54 mostly former British colonies, meeting in the Australian city of Perth, supported less than half the reform measures recommended by a group of eminent persons.

A key proposal to set up a commissioner for human rights was opposed by several leaders, including those from South Africa, India and Sri Lanka.

“With these discussions and the significant reforms we have agreed, I believe we’ve made a major contribution towards ensuring the Commonwealth is an institution that is well-positioned for the future,” Australian Prime Minister Julia Gillard told reporters on the final day of the summit.

But critics said those measures fell short. They pointed out that Sri Lanka would be hosting the next Commonwealth summit in 2013. Canada has already threatened to boycott that meeting unless Sri Lanka improves its human rights record.

In its final communique, the Commonwealth committed to helping small island states, which make up more than half of its membership, cope with the effects of climate change and said there was a need to work towards legally binding measures like the UN Framework Convention on Climate Change.

Many small island nations fear being wiped off the map by global warming and were pressing for a strong statement ahead of the international summit on climate change in South Africa next month.

“Climate change issues are not something that is happening in the future. It is happening now and we must deal with it now,” Mohamed Nasheed, the president of the small island nation of Maldives said. He applauded Australia’s recent carbon tax as a model for other nations.

The Commonwealth failed to take action on two other issues on its agenda — child brides and HIV/AIDS. Twelve of the 20 countries with the highest rates of child brides are in the Commonwealth.
