Theresa May calls for renewed action to tackle modern slavery

Former Prime Minister Theresa May has urged world leaders to prioritise the fight against modern slavery, warning that progress has stalled.

Speaking at the launch of the Global Data Partnership Against Forced Labour, May stressed the urgent need for international collaboration, improved data-sharing, and stronger enforcement to combat the growing crisis.

Modern slavery affects over 50 million people worldwide, with forced labour generating an estimated $236 billion in illegal profits annually, according to the International Labour Organisation (ILO).

May highlighted that despite international commitments, the issue has slipped down the political agenda in recent years: “The reality is that modern slavery remains one of the greatest human rights challenges of our time. We need to restore momentum and take decisive action,” she said.

May also emphasised the role of technology, including AI, machine learning, and blockchain, in identifying hidden patterns of exploitation and supporting victims. Such tools could help disrupt trafficking networks and strengthen corporate accountability.

The Global Commission on Modern Slavery and Human Trafficking, which May supports, is focusing on forced labour in supply chains, effective national implementation of anti-slavery commitments, and better civil society engagement. She called for a cross-sectoral approach, ensuring governments, businesses, and organisations work together to embed anti-slavery measures in global supply chains.

“This is not just a moral imperative but an economic necessity. Strong legislation, good governance, and coordinated action are vital,” May concluded.
