The man can surely speak for himself...
"In today's backbench business debate the House spoke on the subject of tax avoidance, a subject that I have been pursuing with vigour over the last few months.
I took the opportunity today to name and shame technology companies who have Government contracts,
yet do not pay their fair share of tax. Some don't pay any tax at all. It's a real insult to hard working people who struggle to get by yet still pay their fair share of taxes."
