It means that if the government were, as I suggest, to fund a £30 billion (2% of GDP) investment programme, and fund it by borrowing through issuing long-term index-linked gilts, the cost to taxpayers - the interest on those gilts - would be something like £150 million a year. To put this in perspective, it's roughly the revenue the OBR estimates will be raised by the "loophole-closing VAT measures" in the last Budget. In other words, we could fund a massive job-creating infrastructure programme with the pasty tax."
