Yesterday we learned that Starbucks, which had sales of nearly £400m in the UK last year, paid nothing in corporation tax.
This is down to something called "transfer pricing". It sounds complicated, and in fact it is, but in a nutshell it's a process by which large companies move money off-shore as a way to avoid paying pax on it.
This is legal, but it's not an option for smaller independant producers who are then at a huge disadvantage.
We want to tell Starbucks that they have an obligation, if they want to make money in the UK, to pay their fair share of tax.
