Tax avoidance, evasion and international transparency were the central topics at this week's G8 summit in Fermanagh, Northern Ireland - but it was a case of talk and not much action as the Prime Minister failed to persuade colleagues to make any binding decisions .
Cameron outlined plans for a global strategy to combat tax evasion in a communique, including governments sharing tax information between countries.
Also included in the Lough Erne Declaration were plans for a UK register of beneficial ownership, which could be available to the public.
The register would require owners of offshore shell companies, including subsidiaries, to identify their effective owners by registering them with Companies House.
In a press conference, the Prime Minister said that tackling tax evasion and "abusive" avoidance is top of the UK's agenda.
