Surely Parliament should vote before trashing the currency?

A report in This is Money, linked here, states that the MPC of the Bank of England voted 9-0 in favour of printing money without resources thus trashing all our pensions and savings. The article states that this will proceed on receipt of a letter from the expenses fiddling Scot Alistair Darling, I quote: The minutes said: 'The committee unanimously agreed the Governor should write on its behalf to the Chancellor to seek authority to conduct purchases of government and other securities, financed by the creation of central bank money.' What is Parliament for if not to at least have a vote to prevent such a disgusting betrayal, destroying at a stroke the hard work and savings of millions of citizens?
