According to the FT:

David Cameron on Wednesday urged European leaders to be in the vanguard of a global effort to crack down on aggressive tax avoidance and evasion, as he tries to build momentum before the G8 summit in Northern Ireland in June.

As a result:

Mr Cameron called on governments to “break through the walls of corporate secrecy” by making information on the beneficial ownership of companies available in public registries.

“A lack of knowledge about who ultimately controls, owns and profits from companies leads to aggressive tax avoidance, tax evasion and money laundering, undermining tax bases and fuelling corruption across the world,” he said.

I could not agree more, but the isue starts at home Mr Cameron. As my research has shown, the UK company register is not just badly managed, it's an open opportunity for tax fraud. If Cameron was serious he'd be investing heavily in Companies House. Instead it has had 25% staff cuts.
