As American fund raisers debate the Obama administration’s plan to limit the charitable tax deductions for the wealthy, a vastly different tax proposal is roiling the United Kingdom.

The Fortune Forum, an organization that puts together an annual meeting in London of philanthropists and celebrities to promote giving, started an advocacy campaign this week to have the government provide lucrative tax breaks to rich people and companies that donate to help the world’s poor.

Specifically, the proposal would allow 50 percent tax relief on contributions that support the United Nations Millennium Development Goals, a set of antipoverty and social goals, reports The Guardian, a British newspaper.

The forum said its plan, which was crafted by James Mirrlees, a Nobel Prize-winning economist, would spur an additional $7-billion a year for charity.

The proposal appears to have divided Britons. Marina Hyde, a columnist for The Guardian, bashes the idea in an opinion article, saying it would supplant the government’s foreign aid budget and is a glorified tax haven for the rich.

Matthew Bishop and Michael Green, the authors of Philanthrocapitalism, defend the plan in a separate article in the newspaper. They argue that instead of mocking wealthy donors, the critics should consider what philanthropy has accomplished in America.
