The Drum: WPP boss Sir Martin Sorrell claims ‘chickens have come home to roost’ over tax scandals

The head of advertising giant WPP has questioned the “judgment” of companies such as Google, Amazon and Starbucks accused of utilising “very aggressive” schemes to minimise their tax outputs in the UK.

Speaking to the Mirror, Sir Martin Sorrell said: “You can push the rules, you can abide by the laws, you can lower your tax rates. But should you do it from a question of judgment? “The chickens have come to roost because people have been very aggressive on their tax planning. Some people have judged it right, some people have judged it wrong.”
