'Pandora papers' show London is a key hub for tax avoidance

London: Transparency advocates are calling on Britain to tighten the country's defenses against money laundering and tax avoidance after a massive leak of financial data showed how London is a key destination of choice for some of the world's richest and most powerful people to conceal their cash.

The cache of almost 12 million files shows how wealthy people around the world reportedly set up offshore companies to buy property and avoid taxes.

Foreign individuals identified as beneficiaries of these types of offshore accounts in London include Jordanian King Abdullah II, Azerbaijan's President Ilham Aliyev and associates of Pakistani Prime Minister Imran Khan. Abdullah has denied any impropriety and Khan tweeted that his government would investigate anyone mentioned and take appropriate action if wrongdoing is found. Aliyev hasn't commented.

The leaked financial data, dubbed the Pandora Papers, was published Sunday by the International Consortium of Investigative Journalists and its media partners, including Britain's Guardian newspaper and the BBC.

Though the purchases are legal under British law, they highlight the complicated and often anonymous financial practices wealthy individuals use to avoid tax, far removed from the everyday experience of most of the British population.

London is a go-to for the rich and powerful because it's home to a sophisticated ecosystem of businesses that can help in the process, including creative wealth management firms, high-end lawyers and long-established accounting firms. A 2019 analysis by transparency group Global Witness indicated that around 87,000 properties in England and Wales were owned by anonymous companies registered in tax havens.
