We, and our politicians, love to moralise about the rank unfairness of multinational corporations paying so little tax. And it's quite understandable we should. As we suffer austerity measures on one side and higher food and energy bills on the other, why should multinational corporations get off so lightly? Well, they shouldn't.

The coffee chain is voluntarily paying £20m to the UK taxman - an action that has been celebrated as a victory over the multi-nationals, promising to have a ripple effect on other tax dodgers. But will it?

The global financial elite is operating in a mirror world, one in which black is white and up is down but, as Nigel Green makes clear, to do so would be a gross dereliction of duty to your shareholders.

Those of us who campaign for the powerful to pay their taxes are delighted with the cross-party MPs' report because it sets out the shocking facts on tax and poverty with admirable clarity. It also calls on the Government to stop making excuses and get on with helping poor countries collect the taxes they're owed.

The chorus of voices in protest is growing. How loud will it have to get before we see some change?
