I appreciate the Prime Minister having the stomach to say that out loud, but everyone knows that it is the Tory party’s obsession with wild, unfunded tax cuts that crashed the economy. We know it, he knows it and his party knows it, and the whole country is living it. When is he finally going to learn the lesson from his predecessor’s mistakes and explain where the money is coming from for his own completely unfunded £46 billion promise to scrap national insurance?
