On 22 November 2012, peers took part in a debate called by Liberal Democrat Baroness Nicholson of Winterbourne on the Millennium Development Goals.
The Millennium Development Goals are a set of targets to reduce global poverty and improve living standards by 2015.
David Cameron has said there is a "real opportunity" to end extreme global poverty within the next few decades.
Mr Cameron has been asked by the UN to look into how poverty in developing countries should be tackled after 2015.
Earlier this month he co-chaired the first meeting of the United Nations panel, along with Liberian President Ellen Johnson Sirleaf and the Indonesian president Susilo Bambang Yudhoyono.
Progress on the Millennium Development Goals has been patchy. The first of the goals - reducing poverty among some of the very poorest - has been achieved, due largely to big increases in income in recent years in China and India. But attempts to reach other goals have been less successful.
Mr Cameron said there needed to be a renewed focus on tackling the causes of poverty - highlighting the importance of reducing corruption, promoting the rights of women and minorities and backing freedom of expression and association.
