David Cameron has secured an agreement from Britain's network of overseas territories and Crown dependencies to sign up to a new clampdown on tax evasion.
At talks at Downing Street ahead of next week's G8 summit at Lough Erne, the leaders all agreed to a series of actions aimed at promoting transparency and exchange of information between tax jurisdictions.
The Prime Minister hailed the agreement as a "very positive step forward" which would strengthen his hand in talks with the other G8 leaders in which he has made improving international tax compliance a key issue.
