Mobile telecommunications firm Vodafone said it did not pay corporation tax in the UK for the year to March 2013, even though it generated over £5bn in revenues in the country.
The company, which paid more than £2.5bn in corporate tax in other countries, said it is committed to acting with integrity in all tax matters.
"We always seek to operate under a policy of full transparency with the tax authorities in all countries in which we operate, disclosing all relevant facts in full, while seeking to build open and honest relationships in our day-to-day interactions with those authorities," the company said.
"We also invested more than £6 billion in the networks and services now relied upon by more than 400 million customers worldwide," Vodafone said.
Major companies like Google and Starbucks have faced scrutiny in the UK over their tax affairs in recent months and have even asked by legislators to explain their corporate tax contribution.
