Google executive chairman Eric Schmidt has once again defended the company's tax affairs in Britain by saying that it will pay more tax in the UK if the country's tax laws are changed. Schmidt told BBC Radio 4 that if Britain wanted to collect more tax, it should change the law. "What we are doing is legal. I'm rather perplexed by this debate, which has been going on in the UK for quite some time because I view taxes as not optional. I view that you should pay the taxes that are legally required," Schmidt said.
