No single politician has ever put tax up more times than the Prime Minister has. But hang on, he was just given the chance to rule out cutting the NHS or state pensions to pay for scrapping national insurance. I was a lawyer long enough to know when someone is avoiding the question, so I am going to give him another chance. Will he now rule out cuts to the NHS, cuts to the state pension or putting up taxes to pay for his unfunded £46 billion promise to scrap national insurance? Which is it?
