it is done independently by hmrc but i'm absolutely clear that no government has done more than this one to crack down on tax evasion and aggressive tax avoidance, no government and certainly not the last labour government. >> mr. speaker, my question actually was if the prime minister thinks an effective tax rate of 3% is right or wrong. he didn't answer it. while the prime minister only called it a step forward. the mayor of london described it and what exactly is the position on for 3% tax rate? >> more tax in future than they ever paid under labour. whether tax rate for google was zero percent. let me tell you what we have done, we have changed the tax laws so many times that we raised an extra 100 billion from business in the last parliament. when i came to power, banks didn't pay tax on profits, allowed under labour, investment companies could cut their tax bill by flipping the currency their accounts were in, allowed under labour, companies could fiddle accounting rules to make losses appear out of thin air. we've done more on tax evasion than tax avoidance than labour did. th
