Is the Bank of England threatened by politics?

Prime Minister Theresa May has been critical of the Bank of England's stimulus scheme for the UK economy - know as quantitative easing, or QE. In her speech to the Conservative Party conference, she said that under QE, "people with assets had got richer, people without them had suffered".

Deputy governor of the Bank of England, Ben Broadbent told the Today programme's Katie Prescott the measure is the remit given them by parliament and they "take the best possible decision they can at any one point in time".
