The campaign organisation UK Uncut says that planned protests outside 40 Starbucks stores will take place this weekend, despite the organisation offering to pay £10 million pounds in corporation tax.
Spokeswoman Hannah Pearce said that offering to pay some tax "if and when it suits" did not stop the company being a tax avoider.
"Today's announcement is just a desperate attempt to deflect public pressure" she continued.
"There is no money yet, and hollow promises on press releases don't fund women's refuges or child benefits."
