The UK government must use the Open Government Partnership summit in London next week to end the secrecy surrounding who really owns millions of UK companies...Failure to do so would be a massive missed opportunity to stop tax evasion, money laundering and other forms of crime and corruption, and would seriously undermine UK government claims to lead the world on government openness and accountability...Chris Taggart, Co-Founder & CEO, OpenCorporates said: “In a globalised world, with transnational corporations increasingly dominant, ownership transparency is also critical for democracy."...Joseph Stead, Senior Adviser on Economic Justice at Christian Aid said: “Phantom firms registered in developed countries, like the UK and its overseas territories, facilitate huge outflows of illicit money from developing countries. Ending the secrecy will help stop the outflows and ensure developing countries have the resources to provide for essential public services such as health and education.”
