Starbucks' tax payment is 'unfair' say independent cafes
US coffee giant Starbucks reportedly paid just £8.6m in corporation tax in the UK over 14 years.
The four-month investigation by news agency Reuters also found the firm had paid nothing in the last three years.
Starbucks UK reported losses so did not have to pay corporation tax, but told investors that it was "profitable".
"We have paid and will continue to pay our fair share of taxes in full compliance with all UK tax laws, as we always have," Starbucks said.
Newsnight's Joe Lynam investigates, and asks whether a mini-boycott of the coffee giant could be brewing.
