Kwasi Kwarteng claimed his tax cuts “favour people right across the income scale” amid accusations they mainly help the rich, and hinted more are on the way.
The Chancellor defended his programme of tax cuts – the biggest for 50 years – which he announced on Friday using more than £70 billion of increased borrowing.
Analysis suggests the measures, which include abolishing the top rate of income tax for the highest earners, will see only the incomes of the wealthiest households grow while most people will be worse off.
But Mr Kwarteng insisted he is “focused on tax cuts across the board”.
