The chairwoman of the Commons Influential Public Accounts Committee has said its "an outrage" that the retail giant Amazon paid only £10m in tax in 2013, after reporting record sales of £4.3 billion.
"It is an outrage," chairwoman Margaret Hodge told the Herald Scotland, "Amazon should pay their fair share of tax.
"They are making money out of not paying taxes. I no longer use Amazon."
Amazon insists it follows the tax rules in all the countries where it operates.
Amazon paid £10 million corporation tax in Britain last year, despite achieving record sales of £4.3 billion.
The US company's UK arm is registered to pay tax in Luxembourg, meaning it can avoid higher rates of tax.
Amazon.co.uk reported a 56% rise in profits to £17 million last year on a 13% rise in UK revenues.
Essex University's Professor of Accounting, Prem Sikka, said this may have put the company "under pressure from HMRC to adjust their inter-company agreements."
Amazon said it follows all the tax rules in every country where it operates. HMRC declined comment.
Online retailer Amazon has announced a new partnership that will allow customers to shop via Twitter.
With the new system users add the hashtag #AmazonBasket to tweets referencing products they like, then the item is automatically added to their online shopping cart.
Amazon said the tie-up would mean "no more switching apps, typing out passwords or trying to remember items you saw on Twitter".
Amazon has launched an online grocery service called Prime Pantry that lets US members of its Prime loyalty scheme do their food shopping on the website.
The service allows members to fill a 45-pound (20kg) box of groceries and have it delivered to them for a flat fee of $5.99 dollars (£3.56) - though fresh food is not available through the service.
The Amazon website says: "Adding your first Prime Pantry item to Cart starts a Prime Pantry box. As you shop, you see that each Pantry item tells you what percentage of a Pantry box it fills based on its size and weight.
"Pantry boxes are large and can hold up to 45 pounds or four cubic feet of household products. As you check items off your list, we continuously track and show you how full your box is."
The service - which is currently only available in the US - is the latest in a line of new services Amazon has recently launched to compete with rivals such as Apple and Google.
A series of pictures of a remote, uncontacted tribe in the Amazon basin has been released. The pictures were taken near the Xinane river in Brazil's Acre State, close to its border with Peru.
The tribe was first identified as "uncontacted" in 2011 when satellite pictures revealed this community was living near the border with Peru.
In the latest pictures, taken on March 25, the uncontacted people are seen reacting to a plane flying overhead. As many as five tribal men can be seen raising their weapons in a threatening manner at the plane.
Online retailer Amazon is testing unmanned drones called Octocopters in a bid to deliver packages to customers within 30 minutes.
The drones could deliver packages that weigh up to 2.3kg but the service is not expected to start for at least five years, the company's chief executive Jeff Bezos claimed.
Mr Bezos told CBS television's 60 Minutes programme: "These are effectively drones but there’s no reason that they can’t be used as delivery vehicles...I know this looks like science fiction. It’s not."
"We can carry objects, we think, up to five pounds, which covers 86 per cent of the items that we deliver...These are electric motors, so this is all electric; it’s very green, it’s better than driving trucks around," he added.
The service will be called Prime Air but US aviation officials have not approved use of the drones.

The author of a book that advocates beating children under a year old with paddles said he was "delighted" to discover a Tory MP was calling for it to be banned on Amazon's website.
Michael Pearl told BBC Radio 5 Live that if the book is removed from the retailer's website, he will "advertise it as 'the book banned in the UK'".
Mr Pearl told the radio station: "I was delighted to hear that Parliament might ban my book, if they do, I will immediately advertise it as 'the book banned in the UK' and...we will end up selling another 100,000 books directly to the UK."
"The British defeated the Nazi's with planes and tanks and now they stoop to defeating ideas with censorship," he added.
Conservative MP Nadine Dorries asked House of Commons leader Andrew Lansley to bring the issue of a book that "advocates the beating of children" to Parliament in a bid to pressurise Amazon into removing it from their website.
I'm rising to ask you if you can use your good office to apply pressure on an issue which has come to my attention in the last 24 hours.
It's regarding a book which is for sale on Amazon called To Train Up A Child by Michael and Debi Pearl. It actually advocates the beating of children under the age of 12 months using a switch.
The book recommends that switch be cut from a willow tree and be no longer than 12 inches in length and 8cm in diameter.
The book advocates the use of paddles, rulers and other means to beat children from four months onwards.
Conservative MP Nadine Dorries has urged Amazon to remove a book that advocates beating children under a year old with paddles, rulers and implements fashioned from trees.
The controversial book To Train Up A Child should be taken off the online retailer's website as it advocates child abuse, Ms Dorries said.
The book's authors, Debi and Michael Pearl, run their own No Greater Joy Christian ministry and Mr Pearl describes himself as a "pastor, missionary, and evangelist for over 40 years", according to his website.
Ms Dorries asked Commons leader Andrew Lansley to bring the issue to Parliament to apply pressure on Amazon to remove the book, first published in 1994, from sale.
