Both internet giants have been criticised in recent months for making substantial sales in the UK, but only paying a small amount of tax to the Treasury - as little as 1.5 percent on hundreds of millions of pounds in some instances.

According to a Reuters report, the Public Accounts Committee has asked senior officials from the companies to address a hearing on 5 November. However, this could be delayed due to scheduling issues.

It is thought that Google's representative will be UK managing director Matt Brittin.

In the six years leading up to the end of 2010, Google had paid a total of £8 million of corporation tax in the UK. Amazon, on the other hand, is asking its publishers to pay a full 20 percent of VAT on ebook sales in the UK - even though it only has to pay 3 percent to the Exchequer because it is based in Luxembourg.

This amounts to an extra £1.38 profit every time it sells a £10 ebook in the UK.
