Some of the world's richest nations are within touching distance of a historic deal to close the net on large companies that do not pay their fair share of tax, France and Germany said on Friday after a day of talks in London.

Finance ministers from the Group of Seven rich nations are meeting in person for the first time since the start of the COVID-19 pandemic, after U.S. President Joe Biden's administration gave fresh impetus to stalled global tax talks this year.

Rich nations have struggled for years to agree a way to raise more tax from large multinationals such as Google, Amazon and Facebook, which often book profits in jurisdictions where they pay little or no tax.
